 The MCP1623/24 is a compact, high-efficiency, fixed frequency, synchronous step-up DC-DC converter. It provides an easy-to-use power supply solution for PIC microcontroller applications powered by either one-cell, two-cell, or three-cell alkaline, NiCd, NiMH, one-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 input. High efficiency is accomplished by integrating the low resistance N-Channel Boost switch and synchronous P-Channel switch. All compensation and protection circuitry are integrated to minimize external components. For standby applications, the MCP1624 operates and consumes only 19 µA while operating at no load. The MCP1623 device option is available that operates in PWM-only mode. A “true” Load Disconnect mode provides input to output isolation while disabled (EN = GND) by removing the normal boost regulator diode path from input to output. This mode consumes less than 1 µA of input current. Output voltage is set by a small external resistor divider.Datasheet Voltage – Input Offset
