MCP1640BT-I/CHY

The MCP1640/40B/40C/40D is a compact, high-efficiency, fixed frequency, synchronous step-up DC-DC converter. It provides an easy-to-use power supply solution for applications powered by either one-cell, two-cell, or three-cell alkaline, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries. The MCP1640/40B/40C/40D provides very high efficiency through integration of the low resistance N-Channel Boost switch and synchronous P-Channel switch.

MCP1640/40B/40C/40D是一款紧凑型、高效率、固定频率、同步升压DC-DC转换器。它为由单节、两节或三节碱性、NiCd、镍氢、单节锂离子或锂聚合物电池供电的应用提供了易于使用的电源解决方案。MCP1640/40B/40C/40D通过集成低电阻N沟道升压开关和同步P沟道开关提供极高的效率。
