Switching Battery Eliminator Circuit
with interactive input voltage and output load.
Node Label:
* Blue: BB PWM.
* Red: Output voltage.
Input Voltage(vin): 1S to 4S
Ouput Voltage(vout): 5
Max output current: 3S 1A, 3S> 5A
Reference voltage (vref) is based on 1V zener, voltage drop across the diode may change with changing input voltage. To adjust vref adjust the potentiometer wiper value, if output voltage >10 change the zener voltage, vref ratio to vout is 100mV:1V.
PWM sensitivity: 10mV, floor is vref.
PWM max duty: 68.75%
PWM min duty: 0%
