APW7037/A/B

8-PIN Synchronous Buck PWM Controller

Features

General Description

•

Operating with Single 5V or 12V Input

Drives N-Channel MOSFETs

Simple Single-Loop Control Design

− Voltage-Mode PWM Control

− Full 0% to 100% Duty Ratio

− Fast Transient Response

The APW7037 series are designed to provide a low

cost synchronous Buck regulator for on-board DC to

DC converter applications. The APW7037 series to-

gether with dual N-channel MOSFETs such as

APM7313, provide a low cost solution for such

applications. Each device features an internal 200/
