Description
Current sense pin. Connect to the PFET drain
Dimming input pin. When DIM is low, the HG drive is off. Can be connected to a logic level PWM signal
Current feedback pin – to LED cathode. Connect a resistor from this pin to ground to set the DC LED
current
Hysteresis adjust pin. Connect a resistor from this pin to GND to set the hysteresis window
Ground pin
Gate drive output. Connect to the PFET gate
Power supply input
Current limit adjust pin. Connect a resistor from this pin to the PFET source to set the current limit threshold
