The MCP1640 is a synchronous boost regulator designed for high efficiency and low-voltage applications. It operates with a low start-up voltage of 0.65V and can maintain functionality with an input voltage as low as 0.35V. The device supports an adjustable output voltage range from 2.0V to 5.5V, making it versatile for various applications. It features a typical peak input current limit of 800 mA, with specific output current capabilities depending on the input voltage. The MCP1640 operates in automatic PFM/PWM modes, with PWM operation at a frequency of 500 kHz. It has a low quiescent current of 19 µA in PFM mode and consumes less than 1 µA in shutdown mode. The regulator includes features such as true load disconnect, internal compensation, inrush current limiting, and over-temperature protection. It is available in compact SOT-23 and DFN packages, suitable for portable devices powered by single or multiple cell batteries.
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.
