... Intersil VR11.1 controllers and combined with N-Channel MOSFETs, form a complete core-voltage regulator solution for advanced microprocessors. When ISL6620, ISL6620A detects a PSI protocol sent by an Intersil VR11.1 controller, it activates Diode Emulation (DE) operation; otherwise, it operates in normal Continuous Conduction Mode (CCM) PWM mode. ...

... Advanced PWM Protocol (Patent Pending) The advanced PWM protocol of ISL6620, ISL6620A is specifically designed to work with Intersil VR11.1 controllers. When ISL6620, ISL6620A detects a PSI protocol sent by an Intersil VR11.1 controller, it turns on diode emulation operation; otherwise, it remains in normal CCM PWM mode. The controller communicates the tri-state signal to the driver by transitioning the PWM signal from ...

... If VCC drops below the falling threshold of 3.5V (typically), operation of the driver is disabled. Internal Bootstrap Device ISL6620, ISL6620A features an internal bootstrap Schottky diode. Simply adding an external capacitor across the BOOT and PHASE pins completes the bootstrap circuit. The bootstrap function is also designed to prevent the bootstrap capacitor from overcharging due to the large negative swing at the trailing-edge of the PHASE node ...

... The selection of D -PAK, or D-PAK packaged MOSFETs much better match (for the reasons discussed) for the ISL6620A. Low-profile MOSFETs, such as Direct FETs and multi-source leads devices (SO-8, LFPAK, PowerPAK), have low parasitic lead inductances and can be driven by either ISL6620 or ISL6620A (assuming proper layout design). The ISL6620, missing the 3Ω ...
