Dear Milos,
Thanks for the response, within 0.5A is acceptable.

Hi Kevin,

What I can recommend is LM2611 which can deliver up to 400 mA for Vin=12, Vout=-12.

If this is not enough, I will have to ask the engineers form other product lines.

Best regards,
Milos

Dear Milo,
The customer will need to modify the design.
So input voltage will be -48~-54, Vo will be 5V/3.3V ( two rail)
Do you have suitable solution for input up to -54V solution?
Output if have 5V/3.3V rail will be better.
If not, one 12V is acceptable.

Hi Kevin,

I will have to forward this question further, the only thing that comes to my mind is some kind of (multi-output) flyback converter. Until someone responds, please confirm the output current requirements for both cases (12 V and 5/3.3 V).

Best regards,
Milos

Dear Milos,
Appreciated, Vin=-48~-54V, Vo=5V/0.1A, 3.3V/0.3A.
