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.
