High Voltage Synchronous Rectified Buck
MOSFET Driver
The ISL6207 is a high frequency, dual MOSFET driver,
optimized 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, such as ISL6223, ISL6215,
and ISL6216, forms a complete single-stage core-voltage
regulator solution for advanced mobile microprocessors.
The ISL6207 features 4A typical sink current for the lower gate
driver. The 4A typical sink current is capable of holding the
lower MOSFET gate during the Phase node rising edge to
prevent the shoot-through power loss caused by the high dv/dt
of the Phase node. The operation voltage matches the 30V
breakdown voltage of the MOSFETs commonly used in mobile
computer power supplies.
The ISL6207 also features a three-state PWM input that,
working together with most of 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 ISL6207 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
less than a 10ns transition time. This product implements
bootstrapping on the upper gate with an internal bootstrap
Schottky diode, reducing implementation cost, 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.
