ISL6208

DATASHEET ISL6208, ISL6208B High Voltage Synchronous Rectified Buck MOSFET Drivers FN9115 Rev 7.00 July 14, 2014 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. ISL6208 and ISL6208B have the same function but different packages. The descriptions in this datasheet are based on ISL6208 and also apply to ISL6208B. The ISL6208 features 4A typical sinking current for the lower gate driver. This current is capable of holding the lower MOSFET gate off during the rising edge of the Phase node. This prevents shoot-through power loss caused by the high dv/dt of phase voltages. The operat...
