ISL6217 - Precision Multi-Phase Buck PWM Controller

Key Features

  • both input voltage feed-forward and average current mode control for excellent dynamic response, “Loss-less” current sensing using MOSFET RDS(ON) and user selectable switching frequencies from 250kHz to 1MHz per phase. The ISL6217 includes a 6-bit digital-to-analog converter (DAC) that dynamically adjusts the CORE PWM output voltage from 0.700V to 1.708V in 16mV steps and conforms to the Intel IMVP-IV™ and IMVP-IV+™ mobile VID specification. The ISL6217 also has logic inputs to select Active, De.
