The TPS61162A and TPS61163A are dual-channel WLED drivers which provide highly integrated solutions for single-cell Li-ion battery powered smart phone backlight. The devices have a built-in high efficiency boost regulator with integrated 1.5-A, 40-V power MOSFET and support as low as 2.7-V input voltage. With two high current-matching capability current sink regulators, the devices can drive up to 10s2p WLED diodes. The boost output can automatically adjust to the WLED forward voltage and allow very low voltage headroom control, thus to improve LED strings efficiency effectively.

The TPS61162A and TPS61163A support both the PWM dimming interface and one-wire digital EasyScale™ dimming interface and can realize 9-bit brightness code programming.

The TPS61162A and TPS61163A integrate built-in soft start, as well as overvoltage, overcurrent, and thermal shutdown protections.
