TPS61050 Datasheet (Texas Instruments)

TPS61050, Boost Converter

The TPS6105x device is based on a high-frequency synchronous-boost topology with constant current sink to drive single white LEDs.

The device uses an inductive fixed-frequency PWM control scheme using small external components, minimizing input ripple current.

The 2-MHz switching frequency allows th
