Hi team,
We can see the description about PKLMT as below in the datasheet of UCC8070A,
Page-8 [Electrical Characteristics]
Peak current limit threshold: 3.27V (Min.), 3.3V (Typ.), 3.33V (Max.)
Page-20 [7.3.9 Programmable Peak Current Limit]
"The programming range of the PKLMT voltage extends to upwards of 4 V to permit the full use of the 3-V average current sense signal range; however, note that the linearity of the current amplifiers begins to compress above 3.6 V."
Is my understandings as below correct?
-> UCC28070A has the capability of PKLMT to accept 4V, but the recommendation is 3.3V(Typ.) because the linearity is gradually degrading above 3.6V.
Best regards,
Satoshi
