IS31FL3235-QFLS2-TR Description

Short technical summary and product information.

The IS31FL3235-QFLS2-TR is a versatile 28-channel LED driver IC manufactured by Integrated Silicon Solution. Designed for driving LEDs, it offers constant current output for each channel, with the maximum current per channel settable up to 38mA via an external resistor. Each channel's output can be independently scaled by factors of 1, 1/2, 1/3, and 1/4.

 

This device operates within a supply voltage range of 2.7V to 5.5V and functions across an industrial temperature range of -40°C to +85°C. Brightness modulation is achieved through a 256-step PWM duty cycle, controlled via an I2C interface, which also supports an automatic address increment function. The chip can be powered down using a software shutdown feature or by pulling the SDB pin low to conserve energy.

 

The IS31FL3235-QFLS2-TR is housed in a compact 36-VFQFN (4mm x 4mm) exposed pad package, suitable for surface mount applications. Its design makes it ideal for LED display applications in mobile phones, hand-held devices, and various home appliances where precise LED control is required.
