Mobile phone camera flash control circuit
Source: InternetPublisher:张三叔 Keywords: Mobile phone control circuit camera flash Updated: 2021/04/25
The 200mA peak signal current mobile phone camera
flash circuit uses an AAT3110-4.5 capacitive
charge pump chip to boost and stabilize the voltage of the mobile phone
lithium battery
to 4.5V to provide
operating and 100~200mA peak current. The peak current
forms a loop through VF which acts as a flash switch.
The capacitance of the input filter capacitor of the charge pump is lOtiF,
the capacitance of the output filter capacitor is 4.7vF, and the capacitance of the energy storage capacitor is ltiF. Ri,
is the balancing resistance of the light-emitting tube LED. RP is the peak current adjustment
resistor. Adjusting the resistance of RP can set the peak current
