Four-Switch Buck-Boost Development Board(EV44M28A)

The Four-Switch Buck-Boost Development Board (4SW-BB) is a generic development board for this topology that supports rapid prototyping and code development based on dsPIC33 devices.

The board provides organized building blocks that include an input filter, power stage, AUX supply, mating socket for Microchip’s newest Digital Power Plug-In Modules (dsPIC33EP, dsPIC33CK and dsPIC33CH DP PIMs), Human Machine Interface (HMI) and test points. The electrical characteristics are applicable to automotive requirements and can be used for these applications as well.

The 4SW-BB development board can be used along withPower Board Visualizer which is aconfigurable tool running on Windows for visualizing data and controlling individual functions of a connected, external, embedded device through a USB/UART port.
