Description: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 (ISL6
