Part Number: THS6184
can somebody explain why the QFN vs. the HTSOP package has such a high difference:
although both devices have an exposed pad does nto explain the delta of more than 10x
Is there an alternative device providing:
bandwidth is probably too high and current feedback provide high offset, lower woudl be better. Estimated PD *1.2 Watt
In reply to Rohit Bhat:
Received the following updated thermal characheristics to be added to the Datasheet
The PWP (HTSSOP) thermal model is finished, and the θjc to the top of the case = 23.9 °C/W as shown below, which is a little lower than the 27.5 °C/W in the PDS. The θjc to the power pad (bottom of the case) = 1.7 °C/W as shown below.
Apparently, the PDS has the HTSSOP θjc to the top of the case and the QFN θjc to the bottom of the case. I think the HTSSOP should be changed to the bottom of the case. The θJA is more relevant to the customer, and those numbers are close for the two packages as shown below.
