PIN DESCRIPTION

NAME

DESCRIPTION

PIN #

VIN

Input voltage for the IC. Connect a 1uF decoupling

capacitor between this pin and ground.

PWM

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

be used for PWM dimming up to 5 kHz.

ISET

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

Ground return for LED currents and circuitry of the SP7616

LED1-

LED4

Connect an LED between each pin and VIN. Current value

is controlled by RSET. The current level through each pin is

internally matched within 3%. Connect unused channel (s)

to GND to save current consumption.
