ISL6208A ? Data Sheet February 15, 2006 FN9272.0 High Voltage Synchronous Rectified Buck Features MOSFET Driver ? Dual MOSFET Drives for Synchronous Rectified Bridge The ISL6208A is a high frequency, dual MOSFET driver, ? Adaptive Shoot-Through Protection optimized to drive two N-Channel power MOSFETs in a - Active Gate Threshold Monitoring synchronous-rectified buck converter topology. It is - Programmable Dead-Time especially suited for mobile computing applications that ?0.5? On-Resistance and 4A Sink Current Capability require high efficiency and excellent thermal performance. ? Supports High Switching Frequency up to 2MHz This driver, combined with an Intersil multiphase Buck PWM - Fast Output Rise and Fall Time controller, forms a complete single-stage core-voltage - Low Propagation Delay regulator solution for advanced mobile microprocessors. ? Three-State PWM Input for Power Stage Shutdown The ISL6208A features 4A typical sinking current for the ? Internal Bootstrap Schottky Diode lower gate driver. This current is capable of holding the lower ? Low Bias Supply Current (5V, 100μA) MOSFET gate off during the rising edge of the Phase node.
