Part Number: UCC24636 Hi team,
My customer is using our UCC24636, and they find our device have a 540ns turn on delay time.
Please kindly help check if this 540ns is correct? What is the normal range for turn on delay time and how can customer qreduce this…
Part Number: UCC24636 I recently used webench to create an "mains" ac to 5v dc isolated converter (see https://webench.ti.com/appinfo/webench/scripts/SDP.cgi?ID=829567FEA10E90C3)
i noticed that the output has a resister Rpl between 5v+ and …
