ISL6327IRZ-T

Enhanced 6-Phase PWM Controller with 8-Bit VID Code and Differential Inductor  DCR or Resistor Current Sensing

开关控制器 W/ANNEAL 6-PHS VR11 CNTRLR IND

The ISL6327IRZ-T ISL6327 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 components, lower component cost, reduced power  dissipation, and smaller implementation area.

Microprocessor loads can generate load transients with  extremely fast edge rates. The ISL6327IRZ-T ISL6327 utilizes Intersil’s  proprietary Active Pulse Positioning (APP) and Adaptive  Phase Alignment (APA) modulation scheme to achieve the  extremely fast transient response with fewer output  capacitors.
