ISL6336D

DATASHEET ISL6336D VR11.1, 6-Phase PWM Controller with Phase Dropping, Droop Disabled and Load Current Monitoring Features FN8320 Rev 0.00 Oct 6, 2014 The ISL6336D controls voltage regulators by driving up to 6 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. The ISL6336D utilizes Intersil’s proprietary Active Pulse Positioning (APP), Adaptive Phase Alignment (APA) modulation scheme, active phase adding and dropping to achieve and maintain the extremely fast transient response with fewer output capacitors and high efficiency from light to full load. The ISL6336D is designed to be completely compliant with Intel VR11.1 specifications with exception of droop disabled. It accurately reports the load current via the IMON pin to the micropr...
