Other Parts Discussed in Thread: SN6505B
Hi all!
I need to make 5V->5V 2.5-3A isolated DC-DC converter using standard stock components (no custom transformers).
Can I take three identical SN6505B blocks (along with transformers, etc) and connect their outputs in parallel?
Do I need to make some magic with CLK input (provide external clock, etc), or SN6505 running on it's own internal clock (spread spectrum is still useful) is ok?
Maybe just add some bulk capacitance to the output (like 220-470uF) will smooth current spikes and reduce stess?
I've some concerns regarding diodes positive temp coefficiet that can lead to uneaven load distribution.
I can add three diodes to each block output to spread load more evenly.
Any suggestions?
Thanks,
Dmitry
