Panoramica del prodotto

The MCP1624T-I/CHY is a compact high-efficiency fixed frequency synchronous step-up DC-to-DC Converter 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 19µA while operating at no load. 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 1µA of input current.
