High Voltage Synchronous Rectified Buck
MOSFET Driver
The ISL6206 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 Intersil Multi-Phase Buck PWM controller
forms a complete single-stage core-voltage regulator
solution for advanced mobile microprocessors.
The ISL6206 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
reversed-output-voltage damage.
The output drivers in the ISL6206 has the capacity to
efficiently switch power MOSFETs at frequencies up to
2MHz. Each driver is capable of driving a 3000pF load with a
15ns propagation delay and 20ns 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.
