SC46208

SC46208 1.25MHz, 600mA, HIGH EFFICIENCY SYNCHRONOUS STEP-DOWN DC-DC CONVERTER DESCRIPTION SC46208 is a synchronous step-down DC-DC converter with high efficiency. It adopts small flat package. The device features 2.5~5.5V input voltage, 600mA output current, peak current mode PWM and integrated compensation net, which is ideal for powering portable equipment that runs from a single cell Li+ battery without external components. The device integrates an internal switch which eliminates the Schottky diode, 1.25MHz high frequency allows the periphery to adopt SMT inductor and capacitor, thus reduce the size of total solution. It can also run at 100% duty cycle for low dropout operation, that is lower than 1μA shutdown current and 20μA quiescent current in power saving mode. It extends battery life in portable system through increasing the efficiency under light loads. SC46208 is available in an adjustable version and fixed version. www.DataSheet4U.com APPLICATION * Cellular Telephones * PDAs * Wireless Equipment * MP3 player * Digital Camera * Portable Instruments FEATURES * High efficiency up to 95% * Automatic Power Saving Mode at light loads, only 20μA quiescent current. * Wide input voltage range: +2. 5V~+5.5V * Output voltage range: 0.6V~VIN * High output current 600mA * Low dropout operation: 100% * Shutdown current<1μA * 1.25MHz fixed frequency * No Schottky diode required * Thermal shutdown protection * 4KV HBM ESD protection * Small 5-pin SOT-23package HANGZHOU SILAN...
