APW7325

5A 5V 1MHz Synchronous Buck Converter

Features

General Description

• High Efficiency up to 95%

APW7325 is a 5A synchronous buck converter with inte-

- Automatic PFM/PWM Mode Operation

MOSFETs. The APW7325, design with a current-mode

• Integrated 65mΩ High Side / 55mΩ Low Side control scheme, can convert wide input voltage of 2.6V to

MOSFETs

• Low Dropout Operation: 100% Duty Cycle

• Stable with Low ESR Ceramic Capacitors

• Power-On-Reset Detection on VDD and PVDD

6V to the output voltage adjustable from 0.6V to 6V to

provide excellent output voltage regulation.

The APW7325 is equipped with an automatic PFM/PWM

mode operation. At light load , the IC operates in the PFM

mode to reduce the switching losses. At heavy load, the

• Integrated Soft-Start and Soft-Stop

IC works in PWM mode. At PWM mode, the switching
