APW7504A

APW7504/A 1.5MHz, 1.5A Synchronous Buck Regulator Features 1.5A Output Current Wide 3V~5.5V Input Voltage Fixed 1.5MHz Switching Frequency Low Dropout Operating at 100% Duty Cycle 30µA Quiescent Current Synchronous Rectifier 0.6V Reference Voltage <0.5µA Input Current During Shutdown Short-Circuit Protection Over-Temperature Protection Available in TDFN2x2-6 Package Lead Free and Green Devices Available (RoHS Compliant) General Description APW7504/A is a 1.5MHz high efficiency monolithic synchronous buck regulator. Design with current mode scheme, the APW7504/A is stable with ceramic output capacitor. Input voltage from 3V to 5.5V makes the APW7504/A ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable electrical devices. The internally fixed 1.5MHz operating frequency allows the using of small surface mount inductors and capacitors. The synchronous switches included inside increase the efficiency and eliminate the need of an external Schottky diode. The APW7504/A is available in TDFN2x2-6 package.
