Description

The LM51772Q1EVM-HP demonstrates a flexible high power automotive buck-boost design using the LM51772Q1. The evaluation module is configured to operate from input voltage range of 9V to 30V and produce a regulated 12V output with up to 17A load current. The EVM operates with a switching frequency of 400kHz. Most settings of the device can be easily adjusted or set through jumpers, such as: operation mode (PSM or fPWM), bias supply, and external clock synchronization.
