The LM36923H is an ultra-compact, highly efficient, three-string white-LED driver designed for LCD display backlighting. The device can power up to 12 series LEDs at up to 25 mA per string and features an adaptive current regulation method to allow for different LED voltages in each string while maintaining regulation. It supports PWM dimming and I2C control, and includes an auto-frequency mode to optimize efficiency based on load current.
