MOSFET Gate Drive Resistor Selection - Part 2: Turn Off

In this is Part 2 of our mini-series on Power Supply MOSFET Gate Resistors Selection, Dr Seyed Ali Shirsavar of Biricha Digital describes how control to turn off speed of our MOSFET independently of its turn on speed. We show how to design a popular MOSFET turn off circuit, how to select the turn off diode and show some nice experimental results.
