ISL6307 Datasheet 6-phase Pwm Controller

Manufacturer: Renesas

Overview: DATASHEET ISL6307 6-Phase PWM Controller with 8 Bit VID Code Capable of Precision RDS(ON) or DCR Differential Current FN9224 Rev 0.00 March 9, 2006 The ISL6307 controls microprocessor core voltage regulation by driving up to 6 synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer ponents, lower ponent cost, reduced power dissipation, and smaller implementation area. Microprocessor loads can generate load transients with extremely fast edge rates.

Key Features

  • a high bandwidth control loop and ripple frequencies up to 6MHz to provide optimal response to the transients. Today’s microprocessors require a tightly regulated output voltage position versus load current (droop). The ISL6307 senses current by utilizing patented techniques to measure the voltage across the on resistance, RDS(ON), of the lower.
