    RE: UCC38050: UCC38050 PFC based SMPS - operation on 400Hz AC input

    Hello Janos, Thank you for your interest in the UCC38050 TM-PFC controller. To answer your last question first, there is no risk to operate the PFC on a DC input. It will simply act as a boost regulator and the input current waveshape should track...

    RE: UCC28051: 3kHz ripple in AC line current

    Mike, I have previously tried increasing the size of the output capacitance as you have suggested above, I have tested values up to 3X the original value and it had no effect on the 3khz ac line ripple current. Regarding the UCC38050 app note, as...

    RE: WEBENCH® Tools: AC to DC information

    Hi Joey, UCC28810 and TPS92210 can be used for BLDC. They are not limited to lighting applications. For a simpler circuit design, take a look at UCC38050. Take a look at PMP2614: www.ti.com/.../slur561.pdf Best Regards, Ben Lough
