The MCP1630 Dual Buck Reference Design is used to evaluate the Microchip
MCP1630 analog, high-speed Pulse Width Modulator (PWM) used in a dual synchro-
nous, buck regulator, power-converter application. The evaluation board is a complete,
stand-alone, dual-output, dc-dc converter with +12V input, adjustable dual output at
20A per output.
