PIN DESCRIPTION
PIN
NAME
DESCRIPTION
PIN #
VIN
Input voltage for the IC. Connect a 1uF decoupling
capacitor between this pin and ground.
1
PWM
This pin must be held high to enable the output drivers. It can
be used for PWM dimming up to 5 kHz.
2
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
3
GND
Ground return for LED currents and circuitry of the SP7616
4
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.
