The MCP1624/3 are compact, high-efficiency, fixed frequency, synchronous step-up DC-DC converters. Both provide an easy-to-use power supply solution for applications powered by either one/two/three-cell alkaline, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries. The MCP1624/3 can be paired with any PIC® microcontroller bringing flexible intelligence to any single cell or low voltage application.
