UC1825A: Current limit threshold voltage question

David Porter11

Part Number: UC1825A

Current limit threshold voltage is spec'd at .95 to 1.05 volts. I am consistently seeing ~ .88X volts, any idea why?? I am using an output hard off as the threshold.

Hello David,

Are you able to upload your waveforms showing this issue? Is it possible that something else is causing the switching at ~.88V instead of the current limit itself?

Thanks,
Kyle
