General Description
APW7504/A is a 1.5MHz high efficiency monolithic syn-
chronous 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 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.
The APW7504/A is available in TDFN2x2-6 package.
