ISL6219 Product details

Description

VID0, VID1, VID2, VID3, VID4 (Pins 1, 2, 3, 4, 5) 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.When a VID change is detected the reference voltage slowly ramps up or down to the new value in 25mV steps.Connect these pins to either open-drain or active-pull-up type outputs.Pulling these pins above 2.9V can c

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.
