APW7178 General Description

General DescriptionAPW7178 is a 1.5MHz high efficiency monolithic synchronous buck regulator. Design with current mode scheme, the APW7178 is stable with ceramic output capacitor. Input voltage from 2.7V to 6.0V makes the APW7178 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 APW7178 is available in TDFN2x2-6 packages.Features• 1A Output Current• Wide 2.7V~6.0V Input Voltage• Fixed 1.5MHz Switching Frequency• Low Dropout Operating at 100% Duty Cycle• 25μA Quiescent Current• Synchronous Rectifier• 0.6V Reference Voltage• <0.5μA Input Current During Shutdown• Short-Circuit Protection• Over-Temperature Protection• Available in TDFN2x2-6 Packages• Lead Free and Green Devices Available (RoHS Compliant)Applications• HD STB• BT Mouse• PND Instrument• Portable Instrument
