16-BIT COLOR LED DRIVER WITH PWM CONTROL
June 2013
GENERAL DESCRIPTION
The IS31FL3726 is comprised of constant-current
drivers designed for color LEDs. The output current
value can be set using an external resistor. The output
current value can be adjusted from 5mA to 60mA
through the external resistor.
As a result, all outputs will have virtually the same
current levels.
This driver incorporates 16-bit constant t-current outputs,
a 16-bit shift register, a 16-bit latch and a 16-bit
AND-gate circuit.
These drivers have been designed using the CMOS
process.
