Hi,
I have questions about current limit operation.
"Isc" and "OCthresh" are showed as spec in datasheet.
But the detail mean isn't wrote in datasheet.
Could you answer me below questions. please?
Q1 : If load current is over Isc value, How does LM3525 operate?
Q2 : If load current is over OCthresh value, How does LM3525 operate?
At the section of "CURRENT LIMIT" in datasheet, the deference word is used "The current limit threshold"(<- Which is this? Isc or OC?), I can't understand it correctly.
Best regards,
Shimizu
Hi ,
Isc is the current limit threshold, when the output short circuit current will be limit to 1A during this limit period if devcie heat up triger the thermal procetion point then will cycling . The OCthresh is the triger point to current limit behavior .
You can look other device tps2051 to more easy understand this behavior .
