UCC29002: Document Required : for Isolated DC DC Converter Low side Sensing for Load share

Nesh Johny

Part Number: UCC29002
Other Parts Discussed in Thread: LM5022,

Dear Sir,

Could you please share the reference documents for the Load share controller with the current sense resistor on GND/return path.

Also reference document for using this IC in the load share feedback for an Isolated DC DC Converter.  More reference documents are only available for high side current sensing (LM5022 Reference document).

Regards,

Nesh

    Hello Nesh,
    The UCC29002 has an isolated current amplifier and this means the amplifier can be connected to the high side or low side when you wish to measure load current. For example Figure 5 of the data sheet shows a low side current sense and Figure 6 shows a high side current sense application.
    The only difference between the two configurations are the connections for CS+ and CS- but you can see that the differences are self explanatory.
    Hope this answers your question.
    Regards
    John
