High Voltage Synchronous Rectified Buck

MOSFET Driver

The ISL6209 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 ISL6216, ISL6244,

and ISL6247, forms a complete single-stage core-voltage

regulator solution for advanced mobile microprocessors.

The ISL6209 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 ISL6209 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 ISL6209 has the capacity to efficiently switch power

MOSFETs at frequencies up to 2MHz. Each driver is capable of

driving a 3000pF load with a 8ns 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. Programmable dead-time with gate

threshold monitoring is integrated to prevent both MOSFETs

from conducting simultaneously.
