intersil ISL6622A handbook
Update: 30 September, 2023
The ISL6622A is an Intersil high frequency MOSFET driver designed to drive upper and lower power N-Channel MOSFETs to implement a synchronous rectified Buck converter topology. ISL6622A's advanced PWM protocol 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 ISL6622A 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. In the 8 Ld SOIC package, the ISL6622A drives the upper gate to 12V while the lower get can be driven from 5V to 12V. The 10 Ld DFN part allows for more flexibility. The upper gate can be driven from 5V to 12V using the UVCC pin and the lower gate can also be driven from 5V to 12V using the LVCC pin. This provides the flexibility necessary to optimize applications involving trade-offs between gate charge and conduction losses. To further enhance light load efficiency, the ISL6622A enables an additional start-up current control function for reducing EMI.
