Dual 5V Synchronous Buck Pulse-Width

Modulator (PWM) Controller for DDRAM

Features

• Provides V

channel DDRAM memory systems

, V

, and V voltages for one- and two-

DDQ REF

Memory V

and V Termination

DDQ

The ISL6530 provides complete control and protection for

dual DC-DC converters optimized for high-performance

DDRAM memory applications. It is designed to drive low

cost N-channel MOSFETs in synchronous-rectified buck

• Excellent voltage regulation

- V

= 2.5V ±2% over full operating range

DDQ

= (V

÷2) ±1% over full operating range

± 30mV

topology to efficiently generate 2.5V V

for powering

DDQ

for DDRAM differential signalling,

• Supports ‘S3’ sleep mode

- V is held at V ÷2 via low power window regulator

DDRAM memory, V

REF

and V for signal termination. The ISL6530 integrates all of

TT DDQ

to minimize wake-up time

the control, output adjustment, monitoring and protection

functions into a single package.

• Fast transient response

- Full 0% to 100% duty ratio

The V

DDQ

output of the converter is maintained at 2.5V

through an integrated precision voltage reference. The V

output is precisely regulated to 1/2 the memory power

supply, with a maximum tolerance of ±1% over temperature

REF

• Operates from +5V input

• Overcurrent fault monitor on VDD

- Does not require extra current sensing element

and line voltage variations. V accurately tracks V

TT REF

- Uses MOSFET’s r

DS(ON)

During V2_SD sleep mode, the V output is maintained by

a low power window regulator.

• Drives inexpensive N-Channel MOSFETs

The ISL6530 provides simple, single feedback loop, voltage-

mode control with fast transient response. It includes two

phase-locked 300kHz triangle-wave oscillators which are

• Small converter size

- 300kHz fixed frequency oscillator

• 24 Lead, SOIC or 32 Lead, 5mm×5mm QFN

• Pb-Free Available (RoHS Compliant)

displaced 90 to minimize interference between the two

PWM regulators. The regulators feature error amplifiers with

a 15MHz gain-bandwidth product and 6V/µs slew rate which

enables high converter bandwidth for fast transient

performance. The resulting PWM duty ratio ranges from 0%

to 100%.

Applications

• V

, V , and VREF regulation for DDRAM memory

DDQ TT

systems

The ISL6530 protects against over-current conditions by

inhibiting PWM operation. The ISL6530 monitors the current

- Main Memory in AMD® Athlon™ and K8™, Pentium®

III, Pentium IV, Transmeta, PowerPC™, AlphaPC™, and

UltraSparc® based computer systems

in the V

regulator by using the r

of the upper

DS(ON)

- Video memory in graphics systems

MOSFET which eliminates the need for a current sensing

resistor.

• High-power tracking DC-DC regulators

NOTE: Intersil Pb-free products employ special Pb-free material 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-020C.

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