Overview
Global Mixed-mode Technology 1.
4MHz 1A Synchronous 600mA LDO Regulator Buck G5723B Converter with Features Buck Converter „ High Efficiency: Up to 93% „ Low Quiescent Current: Only 50µA During Op- eration „ Internal Soft Start Function „ 1A Output Current „ 2.
5V to 6V Input Voltage Range „ 1.
4MHz Switching Frequency „ No Schottky Diode Required „ 100% Duty Cycle in Dropout Operation „ 0.
6V Reference Allows Low Output Voltages „ <1µA Shutdown Current „ Current Mode Operation for Excellent Line and Load Transient Response LDO Regulator „ Dropout voltage typically 0.
65V @ IO = 600mA „ Output current in excess of 600mA „ Output voltage accuracy ±2% „ Quiescent current, typically 0.
3mA „ Internal short circuit current limit „ Internal over temperature protection Applications „ Digital Still and Video Cameras „ MP3 Players „ Portable Instruments General Description The G5723B consists of a synchronous step-down DC/DC converter and a LDO regulator.
The DC/DC converter is operated on current mode architecture.
Switching frequency is set at 1.
4MHz allowing the use of small surface mount inductor and capacitor.
The internal synchronous switches increase efficiency and eliminate the need for external Schottky diode.
