General Description

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.

The default white LED current is set with the external sensor resistor RFB, and the feedback voltage is regulated to 200 mV, as shown in Typical Application.
