Dual Synchronous Rectified MOSFET Drivers

The ISL6210 integrates two ISL6208A drivers and is optimized to drive two independent power channels in a synchronous-rectified buck converter topology. These drivers combined with an Intersil ISL62xx multiphase PWM controller forms a complete single-stage core-voltage regulator solution with high efficiency performance at high switching frequency for advanced microprocessors.
