PIC microcontroller used in the industrial field, the power supply using switching power supply plus B0505 isolation module, anti-jamming performance is better
Certainly better, or else else to develop this power module why? All with a direct switch power supply! The
There is no direct relationship between isolation and anti-interference.
If you can not remove the interference source, cut off the interference source transmission path is an effective method. Power supply interference can be considered using the power filter.
You use the PIC with which models, switching power supply to the chip power supply is no problem, the key is to single-chip power supply filter to do a good job.
Relay output to use optocoupler isolation and so on. B0505 output test must have a small load and input and output must be added filter capacitor, otherwise interference is great.
