TPS63802 Datasheet (Texas Instruments)

TPS63802, Buck-boost Converter

The TPS63802 is a high efficiency, high output current buck-boost converter.

Depending on the input voltage, it automatically operates in boost, buck, or in a novel 4-cycle buck-boost mode when the input voltage is approximately equal to the output voltage.

The transitions between modes happen at de
