3 Minimal external components arenecessary to develop a complete step-down DC-DCconverter power supply. high converter efficiency is achieved by integrating thecurrent-limited, low-resistance, high -speed N-ChannelMOSFET and associated drive circuitry. Highswitching frequency minimizes the size of externalfiltering components, resulting in a small solution MCP16301/H devices can supply 600 mA ofcontinuous current while regulating the output voltagefrom to 15V. An integrated, high -performancepeak current mode architecture keeps the outputvoltage tightly regulated, even during input voltagesteps and output current transient conditions that arecommon in power EN input is used to turn the device on and turned off.
