Описание
The MCP1640-I/MC is a 0.65V start-up synchronous Boost Regulator with true output disconnect or input/output bypass option. The MCP1640 is a compact high-efficiency fixed frequency synchronous step-up DC-DC converter 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. It provides very high efficiency through integration of the low resistance N-channel boost switch and synchronous P-channel switch. Low-voltage technology allows the regulator to start-up without high inrush current or output voltage overshoot from a low 0.65V input. High efficiency is accomplished by integrating the low resistance N-channel boost switch and synchronous P-channel switch. All compensation and protection circuitry is integrated to minimize the number of external components.
