Overview
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.
Applications
- Mobile phones and other hand - held devices for LED display
- LED in home appliances
Key features
