Constant Current Control

The device regulates the LED output current by monitoring the voltage across a sense resistor on the source of the external MOSFET (CS pin). By operating in Boundary Conduction Mode, the controller turns the MOSFET on when the inductor current drops to zero, eliminating reverse recovery losses in the output diode and optimizing efficiency.

Mistake #3: Poor PWM Dimming Frequency

Many engineers assume a 20kHz PWM signal is fine for dimming. However, the LZC8650C’s DIM pin is optimized for 100Hz to 2kHz. Higher frequencies cause incomplete turn-on/off cycles and distorted brightness. The datasheet explicitly states the acceptable range. You can try searching for the datasheet on
