ISL6219 - Microprocessor CORE Voltage Regulator

Datasheet Summary

Description

These are the inputs to the internal DAC that provide the reference voltage for output regulation.

Each pin has an internal 20µA pull-up current source to 2.5V making the parts compatible with CMOS and TTL logic from 5V down to 2.5V.

Features

  • on the ISL6219 include Dynamic-VID™ technology allowing seamless on-the-fly VID changes with no need for any additional external components. When the ISL6219 receives a new VID code, it incrementally steps the output voltage to the new level. Dynamic VID™ changes are fast and reliable with no output voltage overshoot or undershoot. Like other Intersil multiphase controllers, the ISL6219 uses cost and space-saving rDS(ON) sensing for channel current balance and dynamic voltage positioning. Channe.

® ISL6219 Data Sheet June 2002 FN9080.1 Microprocessor CORE Voltage Regulator Precision Multi-Phase BUCK PWM Controller for Mobile Applications The ISL6219 provides core-voltage regulation by driving up to three interleaved synchronous-rectified buck-converter channels in parallel. Intersil multi-phase controllers together with ISL6207 gate drivers form the basis for the most reliable power-supply solutions available to power the latest industry-leading microprocessors. Multi-phase buckconverter architecture uses interleaved timing to multiply ripple frequency and reduce input and output ripple currents. Lower ripple results in lower total component cost, reduced dissipation, and smaller implementation area. Preconfigured for 3-phase operation, the ISL6219 also offers 2phase operation.
