The LM51770EVM-HV evaluation module (EVM) demonstrates a flexible high-power buck-boost design using the LM51770. The EVM is configured to operate from an input voltage range of 36V to 48V and produce a regulated 48V output with up to 4A load current. The EVM operates with a switching frequency of 380kHz. Most settings of the device are adjusted or set through jumpers, such as operation mode (PSM or fPWM), bias supply and external clock synchronization.
The LM51770 BuckBoost Quickstart Calculator tool supports you defining the power stage using the LM51770 and to select the required external components.
