PRELIMINARY

ISL6597 Integrated Power Stage

Features

The ISL6597 is a high performance power stage for the

highest power density server and workstation buck

regulation solutions. The ISL6597 combined with the

ISL6592 Digital Multiphase Controller offers a complete high

current, small form factor solution with superior accuracy,

transient response, and protection features.

• Highest power density solution available when combined

with the PowerCode™ ISL6592 Digital Multiphase

Controller

• Integrated P-channel high-side FET

• Integrated high and low side drivers

• 30A per power stage capability

The ISL6597 integrates a low r

high-side P-Channel

(DSON)

MOSFET together with both high-side and low-side

MOSFET drivers. The integration of the high-side power

FET with high- and low-side drivers minimizes switching

losses while providing industry leading power density. A

maximum peak output current of 30A per phase is supported

• Discrete low-side FET for best efficiency

• Process and temperature independent lossless integrated

current sense for accurate loadlines and overcurrent

protection

• Integrated high-side short detection protects processor

from over-voltage due to any shorted high-side FET in the

system

in an area less than 16mm , smaller than most discrete

power MOSFETs. The ISL6597 low-side driver supply

(VDRIVE) may be biased separately from the VCC supply

from 5V to 12V to optimize the system efficiency.

• High-side short detect can be used with optional external

SCR crowbar circuit to further protect the processor from

shorted high-side FETs

The ISL6597 has a patent pending lossless current sensor

which accurately senses the current in the high-side FET

independent of VID, inductor value, supply, temperature, and

switching frequencies. This integrated current sense method

provides the accuracy of precision resistor based sensing

with no efficiency loss.

• On-die temperature sense works in conjunction with the

ISL6592 Digital Multiphase Controller to provide accurate

programmable thermal shutdown protection

• Low-side driver supply (VDRIVE) may be separately

biased from 5V to 12V to optimize efficiency

The ISL6597 has an integrated high-side FET short detector

which reacts rapidly on startup to protect the processor

before the controller is powered up. The output high-side

short pins from each phase can drive a single external

crowbar circuitry for rapid protection from a high-side short

on any phase of a multiphase solution. The high-side short

pin also acts as an input, detecting alert signals from every

ISL6597 power stage in the system and protecting each

power stage internally as well.

• 35-ball small form factor CSP package (3.185mm x

4.835mm) provides ultra low thermal resistance

Applications

• Core power regulation for Intel and AMD processors

• Small form factor point-of-load applications

Ordering Information

The ISL6597 also has an integrated junction temperature

sensor which provides an on-die measurement of the high-

side FET temperature. When used with the ISL6592

controller, this feature provides very accurate,

PKG.

35 BALL CSP

programmable over-temperature protection.

The ISL6597 uses CSP packaging to provide the lowest

thermal resistance and smallest footprint. A relaxed 0.65mm

ball pitch allows for easy assembly.

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