Beschreibung
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 (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.For example, input power can be a standard 12V vehicle power rail and operate within the automotive ambient temperature range. A mating socket for dsPIC33 Plug-In Modules allows the system to be evaluated with different controllers.The pinout is compatible for EP,CK and CH dsPIC® DSC DP PIMs.
