ISL95808 High Voltage Synchronous Rectified Buck MOSFET Driver

DATASHEET ISL95808 High Voltage Synchronous Rectified Buck MOSFET Driver FN8689 Rev 2.00 May 25, 2016 The ISL95808 is a high frequency, dual MOSFET driver with low shutdown current, optimized to drive two N-Channel power MOSFETs in a synchronous-rectified buck converter topology. It is especially suited for mobile computing applications that require high .

Features

a 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 operating voltage matches the 30V breakdown voltage of the MOSFETs commonly used in mobile computer power supplies. The ISL95808 also features a three-state .
