ISL6217A - Precision Multi-Phase Buck PWM Controller

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 ISL6217A 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 ISL6217A also has logic inputs.
