The density of portable electronic equipment requires that the design engineer pay particular attention to a number of important design parameters. For power conversion circuitry, two of these parameters are: efficiency and total circuitry footprint. Keeping the efficiency high extends battery life and controls the temperature rise of the equipment. Limiting the circuitry footprint helps minimize the size of the printed circuit board (PCB) and, ultimately, the total cost of the device.

The MCP1612 is an ideal choice for such a design. This application note contains all of the information needed to design a synchronous buck converter using the MCP1612. It also contains a real-world design example with measured laboratory data.
