MCP1640B Description
The MCP1640/B/C/D is a pact, high-efficiency, fixed frequency, synchronous step-up DC-DC converter. It provides an easy-to-use power supply solution for applications powered by either single-cell, two-cell, or three-cell alkaline, NiCd, NiMH, and single-cell Li-Ion or Li-Polymer batteries. Low-voltage technology allows the regulator to start-up without high inrush current or output voltage overshoot from a low 0.65V...
