ISL6614A

DATASHEET ISL6614A Dual Advanced Synchronous Rectified Buck MOSFET Drivers with Pre-POR OVP FN9160 Rev.4.00 May 5, 2008 The ISL6614A integrates two ISL6613A MOSFET drivers and is specifically designed to drive two Channel MOSFETs in a synchronous rectified buck converter topology. These drivers combined with HIP63xx or ISL65xx Multi-Phase Buck PWM controllers and N-Channel MOSFETs form complete core voltage regulator solutions for advanced microprocessors. The ISL6614A drives both the upper and lower gates simultaneously over a range from 5V to 12V. This drive voltage provides the flexibility necessary to optimize applications involving trade-offs between gate charge and conduction losses. An advanced adaptive zero shoot-through protection is integrated to prevent both the upper and lower MOSFETs from conducting simultaneously and to minimize the dead time. These products add an overvoltage protection feature operational before VCC exceeds its turn-on threshold, at which the PHASE n...
