Many Laptops 19v 4.7 amp switch mode ( SMPS ) is working with the 12-volt battery power supply voltage increases the circuit suitable for use in car
Many Laptops 19v 4.7 amp switch mode (SMPS) is working with this power supply circuit suitable for use in upgrading the 12-volt car battery voltage (19v) Control integrated Used UC3843 power MOSFETs is 50N06
In very simple in use Transformer pc power supply circuit EI33 After waiting rip tape on the necessary core to remove the original wrapping in boiling water for 3.5 minutes before you can use the output transformer I remove the bottom of the core, forcing lightly with a cloth and then again waited put 2.3 minutes in water, and I remove the remaining part not on the first try I gave a few fire
Normally I use 1.5mm wire is used wire 10 × 0.5mm that I have 3.5, the problem was removing warmed much wire I used for a long time I've tested with loads of 4.7 amps, but did not issue work but appropriate 10 × 0.5mm winding the start location A + remaining bottom wire coming up + supernatant tip does not work in the opposite end of the FET drain connection will go to the end
Only on departure filter capacitors in the diagram 4x1000uf I use the parts from the first scheme in order to evaluate on my hands I used 2x2200uf
I used a lamp test at 3.5 amps at 4.7 amps while my friend was the victim notebook
