APW7037A/B

8-PIN Synchronous Buck PWM Controller

Features

General Description

The APW7037 series are designed to provide a low cost

synchronous Buck regulator for on-board DC to DC con-

verter applications. The APW7037 series together with

dual N-channel MOSFETs such as APM7313, provide a

low cost solution for such applications. Each device fea-

tures an internal 200/400kHz oscillator, Power-On-Reset

(POR) for both VCC and VC supplies, an external pro-

grammable soft-start function as well as output under-

voltage detection that latches off the device when an out-

put short is detected.

Operating with Single 5V or 12V Input

Drives N-Channel MOSFETs

Simple Single-Loop Control Design

- Voltage-Mode PWM Control

- Full 0% to 100% DutyRatio

- Fast Transient Response

±2% Output Voltage Accuracy Over Temperature

Under-Voltage Protection for Output

200/400kHz Constant Frequency Operation

- 200kHz for APW7037B

- 400kHz for APW7037A
