Other Parts Discussed in Thread: TPS55340,
Hello,
I am considering using TPS55340 to realize a 24V input to -4.2V / 3A continuous output converter.
TPS55340EVM-148 (isolated flyback) has been tested at 24V input to +5V / 2.5A continuous output.
In order to obtain the negative output, I am considering treating the secondary ground as VOUT and connecting the "original" VOUT to primary ground (required in my application).
Does anyone see any issue with doing this (functionally or layout / isolation / noise related)?
If there are better options (cheaper and more efficient) to realize the 24V input to -4.2V / 3A continuous output converter....I am looking at either transformer or "DC isolated" (Ćuk) designs.
Kind regards,
Nitish
p.s. as soon as I entered TPS55340EVM-148 in the part # field, it forced the forum to Non-isolated DC/DC...
