APW7104A

1.5MHz, 1A Synchronous Buck Regulator

Features

General Description

APW7104A is a 1.5MHz high efficiency monolithic syn-

chronous buck regulator. Design with current mode

scheme, the APW7104A is stable with ceramic output

capacitor. Input voltage from 2.7V to 6.0V makes the

APW7104A ideally suited for single Li-Ion battery pow-

ered 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 ex-

ternal Schottky diode.
