Hi Team,
We penetrate our TPS55340 in our customer to build flyback topology. We got several questions and want to double check with you:
1. From our datasheet, the source and sink current on COMP pin is about 42uA:
Not sure if this source current can meet flyback's application which will use a opto which may sink/source current?
As for the opto device:
When operating under higher temp, the Idark will increase from nA to uA, so will this influence the close loop of the fly-back since TPS55340's Isource is only 42uA?
Customer have concern for this and need expert kindly help clarify.
Best regards,
Sulyn
