General Description
APW7506 is a 1.5MHz high efficiency monolithic synchronous buck regulator. Design with current mode scheme,
the APW7506 is stable with ceramic output capacitor. Input voltage from 3V to 5.5V makes the APW7506 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 APW7506 is available in SOT-23-5/TSOT-23-5A
packages.
