Dual Regulator–Synchronous Rectified

Buck PWM and Linear Power Controller

Features

• Provides two regulated voltages

The ISL6529A provides the power control and protection for

two output voltages in high-performance graphics cards and

other embedded processor applications. The dual-output

controller drives two N-Channel MOSFETs in a synchronous

rectified buck converter topology and one N-Channel

MOSFET in a linear configuration. The ISL6529A provides

both a regulated high current, low voltage supply and an

independent, lower current supply integrated in an 14-lead

SOIC package. The controller is ideal for graphic card

applications where regulation of both the graphics

- One synchronous rectified buck PWM controller

- One linear controller

• 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

processing unit (GPU) and memory supplies is required.

- Both outputs: ±1% over temperature - ISL6529AC

- Both outputs: ±2% over temperature - ISL6529C

The synchronous rectified buck converter incorporates

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

±1% over line, load, and temperature ranges for the

ISL6529AC and ±2% for the ISL6529C. Each output is user-

adjustable by means of external resistors.

• 5V down conversion

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

• Simple single-loop voltage-mode PWM control design

• Fast PWM converter transient response

- High-bandwidth error amplifier

- Full 0–100% duty ratio

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

shutdown.

• Linear controller drives N-Channel MOSFET pass transistor

• Fully-adjustable outputs

• Undervoltage fault monitoring on both outputs

• QFN Package:

sets; 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.
