MCP1601

In Production

The MCP1601 is a synchronous Buck (step-down) switching regulator that can continuously supply 500mA of load current. This DC/DC converter can provide output voltages of 0.9V to Vin with an operating efficiency that can exceed 92%. Although ideally suited for a single Li-Ion, or 2 to 3 cell NiCd, NiMH, or alkaline battery operation, the input range of 2.7V to 5.5V is also useful for converting bus voltages to standard system requirements.
