Overview
The MCP16367/8/9 family of devices are highly integrated, high-efficiency, fixed-frequency, step-down DC-DC converters in a compact 8-lead 3x3 mm VDFN package that operates from input voltage sources up to 48V. Integrated features include a high-side switch, fixed-frequency Peak Current Mode Control, Internal Compensation, Power Good, Peak Current Limit and Overtemperature Protection. The MCP16367/8/9 can regulate the output voltage over a wide 2V to 20V range, and typically can deliver over 400 mA of load current at 3.3V output, when supplied from a 12V input. The maximum input voltage range is 4V (after Start-up) to 48V. The regulated voltage (VOUT) should be lower than the input voltage (VIN).
