The TPS61163YFFR from Texas Instruments is a highly integrated dual-channel WLED driver solution for single-cell Li-ion battery-powered smartphone backlights. It features a boost regulator with an integrated 1.5A/40V power MOSFET, supporting input voltages as low as 2.7V.
This device offers two high-current sink regulators, capable of driving up to 10s2p WLED diodes. It boasts excellent current-matching capability with 1% typical accuracy. The boost output automatically adjusts to the WLED forward voltage, enabling very low voltage headroom control (90mV) for improved LED string efficiency.
The TPS61163YFFR supports flexible digital and PWM brightness control, including a 1-wire EasyScale interface and up to a 100:1 PWM dimming ratio with 10-bit resolution. It integrates essential protections such as soft start, overvoltage/current protection, and thermal shutdown. The device is available in a compact 9-DSBGA package, suitable for space-constrained applications.
Key electrical specifications include a 2.7V to 6.5V input voltage range, a 37.5V output capability, a 1.2MHz switching frequency, and up to 30mA LED current per channel. It achieves up to 90% peak efficiency. The operating temperature range is -40°C to 85°C.
