Manufacturer: Intersil (now Renesas)

Overview: NS ESIG D EW R N DUCT O F D RO NDE TUTE P E M STI Data OM 7A Sheet REC EE SUB ISL621 T O S N ® ISL6217 December 2006 FN9089.3 Precision Multi-Phase Buck PWM Controller for Intel‚ Mobile Voltage Positioning IMVP-IV ™ and IMVP-IV+ ™ The ISL6217 Multi-Phase Buck PWM control IC, with integrated half bridge gate drivers, provides a precision voltage regulation system for advanced Pentium“ IV microprocessors in notebook computers. Two-phase operation eases the thermal management issues and load demand of Intel’s latest high performance processors.

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.
