供应IS31FL3218-QFLS2-TR

IS31FL3218 is comprised of 18 constant current

channels each with independent PWM control,

designed for driving LEDs. The output current of each

channel can be set at up to 38mA (Max.) by an external

resistor. The average LED current of each channel can

be changed in 256 steps by changing the PWM duty

cycle through an I2C interface.

The chip can be turned off by pulling the SDB pin low or

by using the software shutdown feature to reduce

power consumption. The slave address is fixed “1010

1000”.

IS31FL3218 is available in QFN-24 (4mm × 4mm) and

SOP-24 packages. It operates from 2.7V to 5.5V over

the temperature range of -40°C to +85°C.
