Hello everyone !
I'm trying to repair the power supply of my Elipson W35 Bluetooth speaker. The problem is that the PWM circuit has no reference "it's a smd marked U4 on the pcb. The reference has been erased at the factory. Here are some photos of the circuit; could you please help me identify the circuit? Thank you, and have a great day
Important point: the resistor R108 marked R100 smd mount is a replacement and I'm note sur if it's the good value, it's relay the mosfet to the ground capacitor 450v
the mosfet is a :SVF12N65F
I also search the reference of the zener diode marked ZD3, I think it's a 15v !?
