General Description

The APW7066 has two synchronous buck PWM

controllers and one linear controller with high

precision internal references voltage to offer accurate

outputs. The PWM controllers are designed to drive

two N-channel MOSFETs in synchronous buck

topology, and the linear controller drives an external

N-channel MOSFET. The device requires 12V and 5V

power supplies, if the 5V supply is not available,

VCC12 can offer an optional shunt regulator 5.8V for

5V supply.

All outputs have independent soft-start and enable

functions by SS/EN pins to control. Connect a capacitor

from each SS/EN pin to the ground for setting the

soft-start time, and pulling the SS/EN pin below 1V to

disable regulator. Pull the SS2/EN2 to VCC, enter the

DDR mode, the SS1/EN1 controls both VOUT1 and

VOUT2, and allows VOUT2 to track VOUT1. It also

offers the phase shift function by REFOUT pin to

select the phase shift between VOUT1 and VOUT2 in

DDR mode or Independent mode. When all SS/EN

pins exceed 3.3V and no faults are detected, the

PGOOD pin goes high to indicate the regulators are

ready. If any of the SS/EN pins goes below 3.2V or

any of the outputs has a fault condition, the PGOOD

pin will be pulled low.

Applications

•

Graphic Cards

DDR memory Power Supplies

Low-Voltage Distributed Power Supplies

The internal oscillator is nominally 300kHz (keep the

FS/SYNC pin open or short to GND), and it offers the

programmable frequency function from 70kHz to

800kHz; connecting a resistor from FS/SYNC to VCC

to decrease the frequency, conversely, connect a

resistor from FS/SYNC to GND to increase the frequency.

The IC also provides the synchronous frequency function.

Connect the LGATE signal of another converter to

FS/SYNC pin; forcing the switching frequency to follow

ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise

customers to obtain the latest version of relevant information to verify before placing orders.
