Description

General part information

TPS63805 Series

The TPS63805, TPS63806, and TPS63807 are high efficiency, high output current buck-boost converters. Depending on the input voltage, they automatically operate in boost, buck, or in a novel 4-cycle buck-boost mode when the input voltage is approximately equal to the output voltage.
