Pin description
Pin #
Pin name
Pin function
1
VOUT
Over voltage protection and supply pin for the IC when V
OUT
> 2 V
2
PWMOUT
Driver of the external MOSFET for PWM dimming. The driver stage is controlled by
EN/PWM signal
EN/PWM signal
3
2Vcc
Charge pump output
4
VCC
Supply voltage when V
OUT
< 2 V, this pin represents the input of the internal charge
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
of 1 µF ceramic capacitor
Exposed Pad
The exposed pad needs to be connected and soldered to analog ground
