The LM251772EVM-PD demonstrates a flexible high-power buck-boost design using the LM251772. The evaluation module (EVM) is configured to operate from an input voltage range of 9V to 36V and to produce a regulated 5V to 48V output with up to a 5A load current. The EVM operates with a switching frequency of 320kHz. Most of the device settings are easily adjusted or set through jumpers, like: operation mode (PSM or fPWM), bias supply, and external clock synchronization.
The LM251772 BuckBoost Quickstart Calculator tool supports you defining the power stage using the LM251772 and to select the required external components.
