2PWMOUT

Driver of the external MOSFET for PWM dimming. The driver stage is controlled by

EN/PWM signal

3

2Vcc

Charge pump output

4VCC

pump

5

FB

Feedback pin for LED current control

6

SENSE

Sense resistor for current mode control and peak current limit

7

EN/PWM

Enable pin and PWM control input for PWMOUT pin

8

GND

Ground reference

9

DRV

Driver output for Boost stage MOSFET

10

V5

Internal regulator output. Decouple this pin locally to the IC ground with a minimum

of 1 µF ceramic capacitor

Exposed Pad

The exposed pad needs to be connected and soldered to analog ground
