VR11.1, VR12 Compatible Synchronous Rectified Buck
MOSFET Driver
ISL6627
The ISL6627 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
ISL6627 is specifically designed to work with Intersil VR11.1,
VR12 controllers and combined with N-Channel MOSFETs to form
a complete core-voltage regulator solution for advanced
microprocessors. When ISL6627 detects a PSI protocol sent by
an Intersil VR11.1, VR12 controller, it activates Diode Emulation
(DE) operation; otherwise, it operates in normal Continuous
Conduction Mode (CCM) PWM mode.
To further enhance light load efficiency, the ISL6627 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.
When ISL6627 detects Diode Braking command from the PWM,
it turns off both gates and reduces overshoot in load transient
situations.
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 user also has the
option to program the driver working in fixed propagation delay
mode to optimize the regulator efficiency. The ISL6627 has a
20k ? integrated high-side gate-to-source resistor to prevent self
turn-on due to high input bus dV/dt.
