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.
