Charger 5V on KP142EH5A with radiator for transistor VT1 and with load resistor. **(WITHOUT LOADING THE OUTLET SCHEME WILL GIVE SAME THAT AND AT THE ENTRANCE !!!)**
Зарядка на 5V на основе кр142ен5а с радиатором для транзистора VT1 и нагрузочным резистором. **(БЕЗ НАГРУЗКИ СХЕМА НА ВЫХОДЕ БУДЕТ ДАВАТЬ...
This is an analogue circuit for a battery charger.
Undervoltage the unit is "hard on" then it oscilates around the desired set voltage forming almost a PWM style switching near full charge.
This circuit pulls about 10ma making the losses to this low.
More efficiency could be obtained from the solar panels using MPPT
