Microchip Technology MCP1601
The MCP1601 is a fully integrated synchronous BUCK (step down) DC/DC converter for battery powered systems. With an input operating range of 2.7V to 5.5V, the MCP1601 is ideal for applications being powered by one single cell Li-Ion, 2 to 3 cell NiMH, NiCd or alkaline sources. The MCP1601 is used to minimize space, cost and wasted energy.| Part No. | MCP1601 |
