ISL6334AR5368 - 4-Phase PWM Controller

Key Features

  • FN6839 Rev 2.00 Sep 7, 2010 The ISL6334AR5368 controls microprocessor core voltage regulation by driving up to 4 interleaved synchronous-rectified buck channels in parallel. This multiphase architecture results in multiplying channel ripple frequency and reducing input and output ripple currents. Lower ripple results in fewer components, lower cost, reduced power dissipation, and smaller implementation area. Microprocessor loads can generate load transients with extremely fast edge rates and r.

DATASHEET ISL6334AR5368 VR11.1, 4-Phase PWM Controller with Light Load Efficiency Enhancement and Load Current Monitoring Features FN6839 Rev 2.00 Sep 7, 2010 The ISL6334AR5368 controls microprocessor core voltage regulation by driving up to 4 interleaved synchronous-rectified buck channels in parallel. This multiphase architecture results in multiplying channel ripple frequency and reducing input and output ripple currents. Lower ripple results in fewer components, lower cost, reduced power dissipation, and smaller implementation area. Microprocessor loads can generate load transients with extremely fast edge rates and requires high efficiency at light load.
