IS31FL3726 16-CHANNEL COLOR LED DRIVER July 2021 GENERAL DESCRIPTION FEATURES The IS31FL3726 is comprised of constant-current Output current capability and number of outputs: drivers designed for color LEDs. The output current 60mA 16 outputs value can be set using an external resistor. The output Constant current range: 5mA to 60mA current value can be adjusted from 5mA to 60mA Application output voltage: 0.4V through the external resistor. For anode-common LEDs As a result, all outputs will have virtually the same Power supply voltage range, VDD = 3.3V to 5.5V current levels. Serial and parallel data transfer rate: 20MHz (Max. cascade connection) This driver incorporates 16-channel constant current outputs, a 16-bit shift register, a 16-bit latch and a 16-bit Operating temperature range, TA= -40C ~ AND-gate circuit. +85C Package: QFN-24 (4mm4mm) and These drivers have been designed using the CMOS eTSSOP-24 process.
