TPS61158 Datasheet (Texas Instruments)

TPS61158, 30-V WLED Driver

With a 30V-rated integrated switch FET and power diode, the TPS61158 is a boost converter that drives LEDs in series.

The boost converter runs at 750-kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use of small external components.
