ISL6247 Datasheet A Mobile Multi-phase Pwm Controller

Manufacturer: Intersil (now Renesas)

Overview: ® ISL6247 Data Sheet June 2003 FN9113 CO NF ID EN TIA L A Mobile Multi-Phase PWM Controller with Precision Current Sensing The ISL6247 provides microprocessor core-voltage regulation by driving up to four interleaved synchronousrectified buck-converter channels in parallel. Multi-phase buck converter architecture uses interleaved timing to multiply ripple frequency and reduce input and output ripple currents. The reduction in ripple results in fewer components, lower component cost, reduced power dissipation, and smaller implementation area. The ISL6247 multi-phase controller together with ISL6207 gate drivers forms the basis for a portable power supply solution to power Intel’s next generation mobile microprocessors.

Key Features

  • Precision Multi-Phase Core Voltage Regulation - ±0.6% System Accuracy Over Temperature.
  • Microprocessor Voltage Identification Input - 6-Bit VID Input - 0.8375V to 1.600V in 12.5mV Steps - Supports VID Changes During Operation.
  • Multiple Current Sensing Approaches Supported - Lossless DCR Current Sensing - Precision Resistive Current Sensing - Low Cost RDS(on) Current Sensing.
  • Excellent Dynamic Response - Combined Input Voltage Feed-Forward and Pulse-byPulse Av.
