Ye fix hai datasheet me

[@roseelectronics4582]

Would it still work if I replaced the step-down transformer with capacitive drop configuration? I sometimes get to repair small house appliances with powersupply problems. I'm thinking of designing small powersupplies to keep at hand so I can immediately replace that part instead of hunting down for the culprit. These powersupplies usually come in capacitive-drop form from the factory. Some of them come with zener diodes at the output in place of the regulators that you're using. I wonder what are the pros and cons for regulators and zeners? One other question is how to calculate and adjust the output power (watts) of these types of applications. Thank you!

[@TEKNOISTIX]

I don't recommend dropping capacitor for variable supply as it is low current and not stable at all
