8-PIN Synchronous Buck PWM Controller

Anpec Electronics 

APW7037A/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

• ±2% Output Voltage Accuracy Over Temperature

• Under-Voltage Protection for Output

• 200/400kHz Constant Frequency Operation

- 200kHz for APW7037B

- 400kHz for APW7037A

• Small size, 8-PIN Package (SOIC or TSSOP)

• Lead Free and Green Devices Available

(RoHS Compliant)

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.
