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 or higher phase(s) when the enable pin (EN_PH) is pulled low.
This simplifies the phase shedding implementation.
For layout simplicity and improving system performance, the device integrates two 5V drivers (ISL6609) and current balance function.
The ISL6611A is designed to minimize the number of analog signals interfacing between the controller and drivers in high phase count and scalable applications.
The common COMP signal, which is usually seen with conventional cascaded configuration, is not required; this improves noise immunity and simplifies the layout.
