MCP1661T-E/OT DC/DC, adjustable, 2.4 ... 5,5 V, 2,4 ... 32 V, SOT-23-5

The MCP1661 device is a compact, high-efficiency, fixed-frequency, non-synchronous step-up DC-DCconverter which integrates a 36 V, 800 NMOS switch. It provides a space-efficient high-voltage step-up power supply solution for applications powered by either two-cell or three-cell alkaline, Lithium, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries.
