MCP1642 Switching Voltage Regulators

Microchip Technology MCP1642 Switching Voltage Regulators are compact, high-efficiency, fixed-frequency, synchronous step-up DC-DC converters. These MCP1642 regulators offer easy-to-use power-supply solutions for applications powered by one-cell, two-cell, or three-cell alkaline, ultimate lithium, NiCd, NiMH, one-cell Li-Ion, or Li-Polymer batteries. Typical applications include personal medical products, wireless sensors, hand-held instruments, and GPS receivers.
