Car DC to DC Converter for laptops
Laptops today are the what is called notebook computers, which now is becoming popular. Laptops can be brought into the bag making it suitable for business trips. And even as the “home entertainment center” laptop is more convenient, because it takes a little space. However, in my opinion, there is one very important which become shortcomings – most laptops which powered by an electric voltage of 19V, making it impossible for them to direct the power to an integrated network vehicle (12-14V). It is very important, especially when laptop battery capacity is not more than two hours in active mode. And what if you, at some object in the whole day want to process some data, but no other useful sources of electricity? This is a description of the relatively simple psu laptop circuit adapter (laptop DC-DC converter), which increases the voltage-board vehicle network to 19V, needed to supply the laptop. And maintain this voltage stable. The adapter is based on chip LM3524, which is a high-frequency switching DC-DC converter with pumped inductance and output current up to 200mA, the output current which, in this scheme, will increased to 3.5-4A using a powerful transistor switch (on transistors VT1 and VT2).
