ISL6622A规格书详情
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.
To further enhance light load efficiency, the ISL6622A
enables diode emulation operation during PSI mode. This
allows Discontinuous Conduction Mode (DCM) by detecting
when the inductor current reaches zero and subsequently
turning off the low side MOSFET to prevent it from sinking
current.
An advanced adaptive shoot-through protection is integrated
to prevent both the upper and lower MOSFETs from
conducting simultaneously and to minimize dead time. The
ISL6622A has a 20kΩ integrated high-side gate-to-source
resistor to prevent self turn-on due to high input bus dV/dt.
This driver adds an overvoltage protection feature
operational while VCC is below its POR threshold; the
PHASE node is connected to the gate of the low side
MOSFET (LGATE) via a 10kΩ resistor limiting the output
voltage of the converter close to the gate threshold of the low
side MOSFET, dependent on the current being shunted,
which provides some protection to the load should the upper
MOSFET(s) become shorted.
