what is purpose of 10K resistors on MOSFET gate to ground?
Thats to safe guard the IGBT/MOSFET from open gate driver ouput fails and turns in to open circuit
what is purpose of 10K resistors on MOSFET gate to ground?
Hey everybody, just saw this circuit and i'm kinda curious as to the specs of the diode going across pins 1 and 8. I'm assuming it's a protection diode of some sort, but what's the voltage and current rating requirements?? Any specific diode that should be used? Thanks guys!
Hi all !!
Here is the schematic SMPS with IR2153 (a better option!). Output voltage and output current at the 300W power supply are 2x35V/2x5A!
Very Good for stereo audio amplifier with TDA7294 !!!
The schematic, given the characteristics of the transformer - the number of windings and polished cross-section of wire.:UP:
Transformer: Ferrite with the intersection of 90...140mm2. Primary hung 40 (2x20) thread with lacquered wire with a diameter of 0.6 mm, secondary thread is 2x10 hanging with a wire diameter of 0.6 mm-triple!
regards and cheers !
