Description

VIN

1

Input voltage for the IC. Connect a 1uF decoupling capacitor between this pin and

ground.

PWM

2

This pin must be held high to enable the output drivers. It can be used for PWM

dimming up to 5 kHz.

ISET

3

Connect resistor RSET from this pin to ground to set output current. Pulling this pin

above the shutdown threshold stated in the Electrical Specifications puts the IC into

shutdown mode.

GND

4

Ground return for LED currents and circuitry of the SP7616.

LED1-4

5 - 8

current level through each pin is internally matched within 3%. Connect unused

channel(s) to GND to save current consumption.
