DATASHEET ISL6622 VR11.1 Compatible Synchronous Rectified Buck MOSFET Drivers FN6470 Rev 2.00 October 30, 2008 The ISL6622 is a high frequency MOSFET driver designed to drive upper and lower power N-Channel MOSFETs in a synchronous rectified buck converter topology. The advanced PWM protocol of ISL6622 is specifically designed to work with Intersil VR11.1 controllers and combined with N-Channel MOSFETs, form a complete core-voltage regulator solution for advanced microprocessors. When ISL6622 detects a PSI protocol sent by an Intersil VR11.1 controller, it activates Diode Emulation (DE) and Gate Voltage Optimization Technology (GVOT) operation; otherwise, it operates in normal Continuous Conduction Mode (CCM) PWM mode.
