Microchip Technology MCP1012 1W Evaluation Board

Microchip Technology MCP1012 1W Evaluation Board (DT100118) is a simple demonstration and development platform for the MCP1012 Primary-Side Start-Up Controller. The MCP1012 is designed to start an off-line flyback converter working in conjunction with a Secondary-Side Controller. The Secondary-Side Controller can be a Microchip Digitally-Enhanced Power Analog (DEPA) device, a PIC-based digital controller, or other. The Secondary-Side Controller’s PIC resources can be made available and interactive to the application load due to being located on the isolated side of the power supply.
