Pin Name

Pin Function

Switch node of boost converter. Connect an inductor between LX and VIN.

GND

Ground.

VOUT

Power output of the asynchronous boost converter for backlight LEDs. Connect a

F or larger ceramic capacitor from VOUT to ground.

VIN

Power input. Connect this pin to the input power supply voltage. Connect a 10

F

or larger ceramic capacitor from the VIN to ground.

PWM
