High Voltage Synchronous Rectified Buck
MOSFET Driver
The ISL6205 is a high-voltage, high-frequency, dual
MOSFET driver specifically designed to drive two N-Channel
power MOSFETs in a synchronous rectified buck converter
topology in mobile computing applications. This driver
combined with an ISL6223 or other Intersil Multi-Phase Buck
PWM controllers forms a complete single-stage core-voltage
regulator solution for advanced mobile microprocessors.
The ISL6205 allows users to select a gate voltage ranging
from 5V to 12V for the lower MOSFET in the synchronous
rectified buck converter. Using a 12V gate voltage reduces
the R
DS(ON)
and the conduction loss in the MOSFET. The
upper gate is required to run at 5V.
The ISL6205 features a three-state PWM input that, working
together with any Intersil multiphase PWM controllers, will
prevent a negative transient on the output voltage when the
output is being shut down. This feature eliminates the
schottky diode that is usually seen in a microprocessor
power system for protecting the microprocessor from any
reversed output voltage damage.
The output drivers in the ISL6205 have the capacity to
efficiently switch power MOSFETs at frequencies up to
2MHz. Each driver is capable of driving a 3000pF load with a
30ns propagation delay and 50ns transition time. This
product implements bootstrapping on the upper gate,
reducing implementation complexity and allowing the use of
higher performance, cost effective, N-Channel MOSFETs.
Adaptive shoot-through protection is integrated to prevent
both MOSFETs from conducting simultaneously.
