... GND OUT FB © 2007 Microchip Technology Inc. with Power-Good General Description The MCP1602 is a high efficient, fully integrated 500 mA synchronous buck regulator with a power- good monitor. The 2.7V to 5.5V input voltage range and low quiescent current (45 µA, typical) makes the MCP1602 ideally suited for applications powered from 1-cell Li-Ion or 2-cell/3-cell NiMH/NiCd batteries ...
