The MCP1624T-I/CHY is a high-efficiency, step-up DC-DC converter by Microchip, housed in a small SOT-23 package. It features an integrated synchronous switch, making it ideal for battery-powered and portable applications requiring a boost voltage.
The MCP1624T-I/CHY is a compact high-efficiency fixed frequency synchronous step-up DC-to-DC Converter that 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 a 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 minimise external components. For standby applications, the MCP1624 operates and consumes only 19A 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 1A of input current.
