The G5177C is a compact, high-efficiency, synchronous step-up converter with power Mosfets embedded and with output turn off true shutdown function and adjustable output current limiting with foldback for a single-cell Li-ion/polymer battery. The G5177C uses only 110μA (typ) quiescent current and allows the converter to switch only when needed at no load and.
Up to 90% Efficiency at Iout=2A VOUT = 5V from 3.3V Input Low 110μA Quiescent Current Guaranteed 3A Output Current at VOUT = 5V from 3.3V Input 500KHz PWM Switching Frequency Synchronous and Embedded Power Mosfets; No Schottky Diode Required Internal Soft-Start to Limit Inrush Current Adjustable Output Output turn off true shutdown function Current Mode Operation with Internal Com- pensation for Excellent Line and Load Transient Response Overload/Short-Circuit Protection with hiccup control Shutdown Current <1µA Thermal Shutdown Compact 8 pin, SOP8 (FD) package Applic.
