To power up the design with a separate bias supply disconnect the diode on the…
Hi Oliver,
Thanks for your interest in UCC28050. The controller is looking at the line voltage through its MULTIN pin. The MULTIN voltage is then fed to a multiplier. The output of the multiplier is compared to the CS pin waveform to determine when…
Hi,
Is the UVLO of the UCC38051,can be rechecked if it can operatye from 11.5V turnon ,or 12V is it?
If not,In this case our device can not be use.B.regards
Eli
