Hi, i need a power supply circuit. I will use it for;
1- Obtain 5V 1A for microcontroller circuit
2- Obtain 12V 1A for backlight
3- Obtain 24-29V 5A for drive dc motors
4- Obtain 100mA constant charge circuit for charge 24V battery

My circuit must work with AC power source and 24v batteries. I designed an simple circuit below. I need your suggestions. Because i cannot on/off my charge circuit by microcontroller.

Best regards

you have to put BC547 in -between your circuit and charger circuit....

collector -> charger circuit on/off pin
base + 1k Resistor to MCU
emitter -> GND

this might help you to on/off this circuit
