Dual Regulator–Synchronous Rectified

Buck PWM and Linear Power Controllers

Features

• Provides two regulated voltages

- One synchronous rectified buck PWM controller

- One linear controller

The ISL6529, ISL6529A provide the power control and

protection for two output voltages in high-performance

graphics cards and other embedded processor applications.

The dual-output controllers drive two N-Channel MOSFETs

in a synchronous rectified buck converter topology and one

N-Channel MOSFET in a linear configuration. The ISL6529,

ISL6529A provide both a regulated high current, low voltage

supply and an independent, lower current supply integrated

in a 14-lead SOIC package. The controllers are ideal for

graphic card applications where regulation of both the

graphics processing unit (GPU) and memory supplies is

required.

• Both controllers drive low cost N-Channel MOSFETs

• 12V direct drive saves external components

• Small converter size

- 600kHz constant frequency operation

- Small external component count

• Excellent output voltage regulation

- Both outputs: ±1% over temperature - ISL6529AC

- Both outputs: ±2% over temperature - ISL6529C

• 5V down conversion

• PWM and linear output voltage range: down to 0.8V

• Simple single-loop voltage-mode PWM control design

The synchronous rectified buck converters incorporate

simple, single feedback loop, voltage-mode control with fast

transient response. Both the switching regulator and linear

regulator provide a maximum static regulation tolerance of

±2% over line, load, and temperature ranges. Each output is

user-adjustable by means of external resistors.

• Fast PWM converter transient response

- High-bandwidth error amplifier

- Full 0-100% duty ratio

• Linear controller drives N-Channel MOSFET pass transistor

• Fully-adjustable outputs

An integrated soft-start feature brings both supplies into

regulation in a controlled manner. Each output is monitored

via the FB pins for undervoltage events. If either output

drops below 51.5% of the nominal output level, both

converters are shut down.

• Undervoltage fault monitoring on both outputs

• QFN Package:

- Compliant to JEDEC PUB95 MO-220

QFN - Quad Flat No Leads - Package Outline

Ordering Information

- Near Chip Scale Package footprint, which improves

PCB efficiency and has a thinner profile

molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with both

SnPb and Pb-free soldering operations. Intersil Pb-free products are

MSL classified at Pb-free peak reflow temperatures that meet or

exceed the Pb-free requirements of IPC/JEDEC J STD-020.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
