ISL6580

Integrated Power Stage

Processors that operate above 1GHz require fast, intelligent

power systems. The ISL6580 Integrated Power Stage is a

High Side FET/driver combination that provides high current

capability per converter phase at high switching frequency.

The chip incorporates intelligence to provide fast transient

response and digital communication to the ISL6590 Digital

Controller. The ISL6580 integrates key power stage

components for fast power delivery, effective thermal design

and increased noise immunity. It incorporates an integrated

P-channel high side MOSFET, high side MOSFET driver

and a driver for external synchronous rectifier, low side

MOSFETs. The ISL6580 also features a window comparator

for fast transient response as well as on-board voltage and

current A/D converters for intelligent digital communication

and control by the ISL6590 Controller.

Furthermore, through the communication bus, configuration

and fault monitoring via the ISL6590 are available.

For more information, see the ISL6590 datasheet.
