16-BIT COLOR LED DRIVER WITH PWM CONTROL

January 2012

GENERAL DESCRIPTION

FEATURES

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.



Output current capability and number of outputs:

60mA × 16 outputs

Constant current range: 5mA to 60mA

Application output voltage: ≥0.4V

For anode-common LEDs

Power supply voltage range, V_DD= 3.3V to 5.5V

Serial and parallel data transfer rate: 20MHz

(Max. cascade connection)



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.



Operating temperature range, T_A= −40°C ~

+85°C



Package: QFN-24

Current accuracy (All output on)

These drivers have been designed using the CMOS

process.
