VFQFPN8

4x4

HS0P8

VINA

Analog circuitry power supply connection

DIM

Dimming control input. Logic low prevents the switching

activity, logic high enables it. A square wave on this pin

implements LED current PWM dimming. Connect to VINA if

not used (see Section 6.6)

Feedback input. Connect a proper sensing resistor to set

the LED current

AGND

Analog circuitry ground connection

Not connected

VINSW

Power input voltage

Regulator switching pin

PGND

Power ground

Exposed pad

Connect the exposed pad to AGND
