Voltage Regulator IC LM1575 with Switched Output Explained

You will be amazed with the features offered by this outstanding voltage regulator IC. As the name refers to, the output from this series of ICs is not only regulated and stabilized but is in the form of switched pulses at very high frequencies. These ICs may be considered as an improved alternative for the conventional 78XX series regulators which tend to become hot with rising currents at their outputs, but not a problem with the series LM2575 from TEXAS INSTRUMENTS.


The switched output with the LM2575 series of ICs especially enables to implement very efficient power transfer to the load even at currents as high 1 Amp.
The switched output saves power, keeps the IC cool so that no heatsinks are involved,  moreover the switched output makes the IC particularly suitable for a wide application range like in LED drivers, battery chargers etc. These will be discussed elaborately in my coming articles.
The LM2575 series from TEXAS INSTRUMENTS provides all the features which particularly becomes very ideal for buck step down regulator applications.
These devices are typically capable of producing fixed regulated outputs of 3.3V, 5V, 12V, 15V, and also an adjustable output from one of the devices.
The configuration around these ICs require very few number of components for enabling it to function as an effective voltage regulator circuit.
The IC necessarily employs an inductor, as we all know that an inductor specifically becomes imperative for all buck/boost type of applications, so even this chip requires one.
Though this inductor my be readily procured from the market, may also be hand made using appropriate sized wire and number of calculated turns.

The main features of the IC LM2575 may be summarized as follows:


Output - 3.3V, 5V, 12V, 15V and also an adjustable version configurable.
The adjustable version is able to provide outputs in the range of 1.2V to 35V, 57 volts being the highest.
Current - A assured 1 amp of current may be expected from these chips.
Input Voltage - A broad DC range upto 40 or even 60 V may be used as inputs for these ICs.
Operating Frequency - The ICs output fluctuates at a fixed frequency of 52 kHz, which is set internally.

Protections - The chips are all internally safeguarded from over heating and over current.

2014 Chevrolet SS

2014 Chevrolet SS
 Information Specification Modification Image Review 2014 chevrolet ss
It was only two months ago first Chevrolet Announced That it was ditching the Impala in next years NASCAR Sprint Cup in favor of an all-new model, one That would also be joining the brands passenger vehicle lineup in the new year.

Immediately this sparked rumors That either the Holden Commodore sedan or its long-wheelbase variant, the Caprice, would form the basis of the new model.

While tight-lipped Chevrolet Remains on the matter, a number of hints have Appeared online recently and this has reportedly Caused the official announcement date to be Brought forward.

According to Australias Drive, an announcement of an export program for the Holden Commodore sedan to the U.S. is imminent, possibly as early as this coming Friday.

Some of the hints That point towards the Commodore being reintroduced to the U.S. market (the car was Previously sold as a Pontiac G8) include the sighting of Several left-hand drive Commodore prototypes testing in Australia alongside the Dodge Charger sedan, the which is sold exclusively in North America.

2014 Chevrolet SS
 On the outside, the SS Performance Ford will take the approach with the Taurus SHO took. It will be very simple, but there will be an element of sexiness to its simplicity. Up front are a set of snake-eye-style fog lamps to help get through the low-laying Those patches of vaporized H20. The upper grille will feature a plastic chicken fence-like pattern, as will the lower grille, but the lower grille is a rectangle and slightly Wider than the upper grille.

At each corner you have a set of 10-spoke, 18-inch alloy rims, that are a polished silver. On the lower part of the rear door there is a Strategically placed "SS" logo on the Holden Commodore SS, the which we would Assume makes its way would to the states.

On the rear end, there is a trunk-mounted spoiler and a set of Altezza-style taillights. Just above the license plate is a little chrome treatment. At the base of the rear bumper, there is a small plastic air dam That has cutouts for the exhaust pipes. The exhaust is a bit of a wildcard, as the Holden Commodore SS has dual exhaust tips, whereas the SS-V models has a set of quad tips (two on each side). The quad tips look sweet, but we Assume only the dual exhaust tips will make it to the States.

2014 Chevrolet SS
 The current Holden Commodore Remains available not just as a sedan, but also as a wagon and ute. Do not count on seeing either variant in the U.S., though Pontiac toyed with the idea in the form of the G8 Sport Truck before the brand died. For now, well be happy with the SS. If its anything like the Dearly Departed G8 GXP to start, were pretty sure Chevy fans will be as well.

INKAS Armored Mercedes G63 AMG

Armored off-road for half the world VIPs
For rich people, the Mercedes G-Class is one of the most popular vehicles. Because the car is sturdy, all-terrain and spacious. The only drawback: Its not a tank. Therefore crosses the company "Inkas Armored Vehicle Manufacturing" from the Canadian Toronto now both types of vehicles. The car not based on the V12 top version G 65 AMG, but still at number two on the model range, the Mercedes G 63 AMG with its 544-hp twin-turbo V8 with 5.5 liter displacement.

Grenades protection in the rear
The passenger compartment offers the armor protection against 7.62-millimeter ammunition and the vehicle floor to explosions and fragments of two simultaneously bursting shells withstand. Furthermore, the wheelbase for the benefit of rear passengers will be extended by about one meter. It contains the Time Stretch range, unlike previous versions, a window, so there are eight side window. Incas used tinted, bulletproof glass. In addition, a matte black finish.

Massage seats and lighting
The customers want, even if it sits in a kind of armor, do not miss a certain luxury go. Therefore, the vehicle interior features luxurious materials such as exotic leathers and rich woods, where one has Bentley, Rolls-Royce and Aston Martin as a model. In addition, an environment was - lighting system integrated into the headliner. It should conjure up various moods in the car with color LEDs - from business mode to various romantic themes. In the rear there are two reclining seats that have been developed specifically for this vehicle. They are equipped with heating, cooling, and a massage system.

Well chilled champagne and gun holder
The rear passengers a view of the partition to the cockpit, in which a large screen and other goodies are integrated. For a well-ventilated and properly sparkling champagne A fridge is. Thus the countless signatures may be inadequate and a special drawer has been integrated. In their place a pin from the limited special edition of Leonardo Mont Blanc course. If the power of the checkbook times is not enough, theres a gun holder, quick access to the weapon granted.

2014 Mercedes G63 AMG

Television cameras and the surrounding area
A satellite phone allows you to make phone calls even in the remotest desert or the worst crisis area. If this is boring times, there are remedies: a satellite TV system with a satellite dish installed on the roof. Is the TV too boring, you can view the environment of the vehicle about cameras you instead. These are operated like most other interior features an iPad mini - obviously the dodgy VIP customers from the half-world of modern technology are open to.

Midsize SUV Sales In Canada June 2014 YTD

2014 Buick Enclave brown
June 2014 was a dreadful month for General Motors in Canada. Year-over-year, total sales fell 15%. GM was outsold by the Ford Motor Company, the Chrysler Group, and the Hyundai-Kia tandem. In the four previous Junes, GM Canada had averaged 25,276 sales. But in June of this year, only 21,007 GM vehicles were sold.

Click Chart To Expand
GMs Lambda platform trio of large, three-row crossovers is a shining example of the June decline. Although Buick Enclave sales were up 7% through the first five months of the year, sales fell 37% in June. 

Chevrolet Traverse sales were nearly chopped in half last month. GMC Acadia volume slid 31%. Not to mention the fact that Saturn didnt sell a single Outlook. *Gasp*

Its not as though Canadians werent buying big crossovers in June. Extract the Acadia, Enclave, and Traverse from the equation and sales in their category improved 4%. 

We dont know if Canadian consumers have suddenly turned away from GM because of the companys self-inflicted recall crisis. GM wasnt the only automaker to report fewer sales in June 2014 than in June 2013 - Hyundai and Kia sales were down 6%. Nor were the trio of Lambda crossovers the only ones in their class to record losses: sales of the Honda Pilot, Jeep Grand Cherokee, and Hyundai Santa Fe XL decreased as well.

But forgetting the overall GM complex for a moment, consider the plight of dealers. They combined to sell 3700 fewer new vehicles last month than at the same time one year ago, 6876 fewer than in June 2012. True, there are fewer GM dealers competing over the companys Canadian sales than their used to be, but GM is also selling far fewer vehicles since Pontiac, Saturn, Oldsmobile, and Hummer disappeared. 

GM Canada sales in 2014 will likely amount to around half the total GM achieved in 2005. Moreover, at this moment the dealers are selling fewer copies of their more profitable vehicles: these crossovers, for example, and their pickup trucks, sales of which slid 17% in June.

These tables are now sortable, so you can rank SUVs and crossovers any which way you like. Suggestions on how GCBC should break down segments can be passed on through the Contact page.

Top 20 Worst Selling Vehicles In Canada June 2014

Now available only via special order, the Nissan Quest was Canadas worst-selling vehicle in June 2014 when measured by year-over-year percentage decline. 

Quest volume tumbled by 132 units to three in June, just 0.04% of the full-size minivan market.


• Canada Vehicle Sales Rankings By Model - June 2014 YTD


Like the Quest, the Dodge Avenger and Nissan Cube and Acura TSX are all cancelled products in Canada. Prospective Avenger buyers are supposed to go look at the new Chrysler 200. However large the small handful of Cube buyers was, they will likely consider the Kia Soul or Nissan Juke. The Acura TSX is, along with the TL, being replaced by the TLX. 

Other vehicles, however, from the Spark to the X1, Q70, Z4, Outlander, Veloster, and Rondo are neither cancelled nor will they be imminently replaced. Canadian sales were chopped in half in June 2014, or worse.

You can always select a make and model at GCBCs Sales Stats page to find historical monthly and yearly sales figures from both Canada and the United States. Pertinent links are clickable at the bottom of this post, but you can also find related links at the Best Sellers page.
