TPS54240: split power

na na78

Part Number: TPS54240
Other Parts Discussed in Thread: TPS62150, , TPS54202

The customer considers following supply.

5V ---> +/- 8V, 0.1A　　①
　　|
---> +/- 15V, 0.1A ②

Referring to SLVA616, positive and negative output supply creation using coupled inductor,
I think ① can be supported by TPS62150 and ② can be supported by TPS54240.

Can you see any problem to my estimation?

I noticed TPS62150 can not generate over 6V output.

Is it possible to use TPS54202 instead of TPS62150?

Hello,

Yes you are right TPS62150 can generate over 6V output. I assumed adjustable verision should be able to, but it seems it can't.

TPS54202 should be able to create required output voltage.
