PIN NUMBER I/O/PWR DESCRIPTION
NAME DRV DRL
PWM 1 6 I PWM input. LED output current is adjusted according to the PWM input duty cycle.
EN 2 5 I Device enable input. Logic high enables the device, logic low disables the device and turns the device into shutdown. Do not leave floating.
VIN 3 4 PWR Power supply input.
SW 4 3 PWR Switch pin. Connecting the internal FET switches and inductor terminal.
GND 5 2 PWR Power ground.
FB 6 1 I Feedback pin for the internal control loop. Connect this pin to an external resistor to set output current.
