Part Number: UC3843 Tool/software: Hi TIer
My customer currently use UC3843 as Isolated power controller, customer wants to upgrade his system to provide 5W and 10W outputs, do we have some models to offer an evaluation?
Also, I would like to ask…
Part Number: UC3843 Tool/software: Hi All,
Is there a configuration that allows me to disable the UC3843 at startup and some time later the mcu will enable it?
Any suggestions would be greatly appreciated.
Thanks,
