intersil ISL6622 handbook

Update: 30 September, 2023

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. In the 8 Ld SOIC package, the ISL6622 drives the upper and lower gates to VCC during normal PWM mode, while the lower gate drops down to a fixed 5.75V (typically) during PSI mode. The 10 Ld DFN part offers more flexibility: the upper gate can be driven from 5V to 12V via the UVCC pin, while the lower gate has a resistor-selectable drive voltage of 5.75V, 6.75V, and 7.75V (typically) during PSI mode. This provides the flexibility necessary to optimize applications.
