... Advanced PWM Protocol (Patent Pending) The advanced PWM protocol of ISL6627 is specifically designed to work with Intersil VR11.1 and VR12 controllers. When ISL6627 detects a PSI# protocol sent by an Intersil VR11.1/VR12 controller, it turns on diode emulation operation; otherwise, it remains in normal CCM PWM mode. Note that for a PWM low to tri-level (2.5V) transition, the LGATE ...

... Internal Bootstrap Device ISL6627 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 excursion ...

... MOSFET driver. Careful layout, proper selection of MOSFETs and packaging, as well as the driver can minimize such unwanted stress. 8 ISL6627 Layout Considerations A good layout helps reduce the ringing on the switching (PHASE) P ⎞ node and significantly lower the stress applied to the MOSFETs as Qg_Q1 • ...
