... Although this pin can be directly connected to the synchronous rectifier (SR) MOSFET gate, the use of gate resistor is recommended (specifically when putting multiple MOSFETs in parallel). Care must be taken in order to keep the gate loop as short and as small as possible in order to achieve optimal switching performance. www.irf.com © 2009 International Rectifier 11 IR1168S ...
