Part Number:LM3429
LM3429 is used for both standing light and flashing light functions:
By controlling 3-pin analog signal and 7-pin PWM signal to achieve two conditions,
1: chang liang;We lower the PWO, that is to say, make the 7-pin voltage greater than 1.24v. At this time, the constant light value changes with the PWM change of 5600-flash-hold.
2: flashing light;We add a fixed PWM value in the 5600-flash-hold. When the MCU (P54 is low) receives a trigger signal, we lower the PWO 20ms and the light flashes.
However, the FLASH value does not change with the value of 5600-flash-hold here. It is always the maximum value!What is the reason?
