ISL6611A Overview
DATASHEET ISL6611A Phase Doubler with Integrated Drivers and Phase Shedding Function FN6881 Rev 1.00 August 28, 2012 The ISL6611A utilizes Intersil’s proprietary Phase Doubler scheme to modulate two-phase power trains with single PWM input. It doubles the number of phases that Intersil’s ISL63xx multiphase controllers can support. At the same time, the PWM line can be pulled high to disable the corresponding phase...
