APW7504R
Active
1.5MHz, 1.2A Synchronous Buck Regulator
Features
General Description
APW7504R is a 1.5MHz high efficiency monolithic synchronous buck regulator. Design with current mode scheme, the APW7504R is stable with ceramic output capacitor. Input voltage from 3V to 5.5V makes the APW7504R 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 APW7504R is available in TDFN2x2-6 package.
