A buck boost converter is a type of DC-DC converter that uses a single inductor, which has an output voltage that is either greater than or less than the input voltage magnitude. This reference design is an evaluation module (EVM) for TPS63050. This EVM is designed to test the operation and functionality of the TPS63050 and TPS63051. The EVM converts a 2.5V to 5.5V input voltage to a regulated 3.3V output voltage that delivers a current of 500mA. Read more
