Integrated Power Stage
Features
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.
• Optimized for Intel VR10 applications
• V = 12V
IN
• Phase switching frequencies of 250kHz to 1MHz
• Phase current capability up to 25A
• High Side P-channel MOSFET
• Low Side MOSFET drivers
• Accurate, lossless, Current Sense
• Programmable MOSFET non-overlap timing (through the
ISL6590 Digital Controller)
• Active Transient Response (ATR) minimizes voltage
droop/overshoot during large load current transients.
Furthermore, through the communication bus, configuration
and fault monitoring via the ISL6590 are available.
• Serial control interface for system monitoring and
configuration (with ISL6590 Controller)
