Integrated features include a high-side and low-side N-Channel switch, fixed frequency Peak Current Mode Control, internal pensation, peak current limit, VOUT overvoltage protection and overtemperature protection. Minimal external ponents are necessary to develop a plete synchronous step-down DC-DC converter power supply. High converter efficiency is achieved by integrating a high-speed, current limited, low resistance, high-side N-Channel MOSFET, as well as a high-speed, low resistance, low-side N-Channel MOSFET and associated drive circuitry. High switching frequency minimizes the size of the inductor and output capacitor, resulting in a small solution size. The MCP16321/2 device can supply...
