Bliss Zhou, hello again!
Unfortunately i can't share waveforms now, due to the virus. I simply can't get to my lab, so i can work only with schematic for now ;( I know, that this new PWM controllers, are much more user-friendly, but i stuck with that…
Part Number: UC3875 Hello team,
Hope you are doing well. Other than packaging are there any other differences between UC3875DWP and UC3875QP?
Regards,
