Overview
APW7104A 1.
5MHz, 1A Synchronous Buck Regulator Features General Description • 1A Output Current • Wide 2.
7V~6.
0V Input Voltage • Fixed 1.
5MHz Switching Frequency • Low Dropout Operating at 100% Duty Cycle • Integrate Synchronous Rectifier • 0.
6V Reference Voltage • Current-Mode Operation with Internal Compensation - Stable with Ceramic Output Capacitors - Fast Line Transient Response • Short-Circuit Protection • Over-Temperature Protection with Hysteresis • Available in SOT-23-5 Packages • Lead Free and Green Devices Available (RoHS Compliant) APW7104A is a 1.
5MHz high efficiency monolithic synchronous 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 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 APW7104A is available in SOT-23-5 packages.
