A lot of 19v Notebook 4.7 amper switch mode (smps) suitable for use in cars that are powered by the power supply circuit 12 volts battery voltage raises (19in) Control IC is used UC3843 the power MOSFET50N06
Transformer pc power supplies used in the circuit is quite simple EI33 Before you can use the output transformer core necessary to remove the original wrapping tape on the boiling water for removing 3.5 minute wait after you took off the lower part of the core with a soft cloth slightly forcing water and then put it 2.3 minutes I waited and took off the rest of the track Volt not the first attempt I gave a few fire

For Notebook 19V 4.7A DCDC Converter
Many Notebook 4.7 amps 19v switch mode (SMPS) power supply is working with this circuit suitable for use in cars is a 12 battery voltage Volt (19in) The integrated control of the UC3843 MOSFET 50N06
The circuit is very simple in use pc power supply Transformer EI33 output of the transformer to use the original winding ago I needed to undo the tape on core disassembly and boiling water in 3.5 minutes, after waiting with a cloth with mild force at the bottom of the nucleus out more then I’ve put into the water and waited 2.3 hours and the rest got off track I gave the first trial did not fire a few
