TPS61197: Can I use 9V-250V?

PAN-M

Part Number: TPS61197

Dear all.

Our customer's request output range is from 9V to 250V at 100mA.
Can we use TPS61197 with transformer for this application?
If there are impotant matters in the design, please teach me.

Regards,

Hi Pan-M,
What is your input voltage? If you want to use transformer, which topology is customer going to use?

Hi Caryss

Input voltage is 8V and toppology is same as Figure 22.
I think that control of Duty is important because an output range is wide.

They seem to be able to make the input voltage 24V.
Can it do this in SEPIC or other topology?

Could you support this?

Hi Pan,
Configuration like Fig 22 could be possible. As for SEPIC, the converter ratio is still too high, using transformer would be better.
