The ISL6208 and ISL6208B are high frequency, dual MOSFET drivers, optimized to drive two N-Channel power MOSFETs in a synchronous-rectified buck converter topology. They are especially suited for mobile computing applications that require high efficiency and excellent thermal performance. These drivers, combined with an Intersil multiphase Buck PWM controller, form a complete single-stage core-voltage regulator solution for advanced mobile microprocessors.
