The ISL6622A 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 ISL6622A 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.
