LP3936SL/NOPB TI LED Driver | 32-TLGA(5.5X4.5) | 36 Outputs, I2C Control

Product Overview

The LP3936SL/NOPB is a highly integrated LED driver from Texas Instruments, designed for portable applications requiring multiple independent LED channels. It features 36 constant-current sink outputs, each programmable via I2C interface, with a maximum output current of 25 mA per channel. The device operates from a 2.7V to 5.5V supply and is housed in a compact 32-pin TLGA package (5.5mm x 4.5mm). It includes built-in PWM control for brightness adjustment and supports pattern generation for animation effects. The LP3936SL/NOPB is ideal for keypad backlighting, indicator LEDs, and decorative lighting in mobile phones, tablets, and other handheld devices.
