LM3481: Overshoot of output voltage at load change(0A<=>100mA)

Part Number: LM3481

Overshoot of output voltage occurs when output load is changed continuously at 0a<=>100mA.

Is there a way to solve this?

I've changed the MLCC of comp and feedback, but it's no use.

Attach a waveform of overshoot.

I'll send you a schematic by your e-mail. Can you give me your address?

Hi David,

Please share your schematic. You may need a dummy load to get the output voltage recovered back to regulation point.

Thank you for your support. Can you give me your e-mail address to send the schematic?

Because the client company does't like to open the schematic.

Thanks

Hi David,

I send you a Friend request and please use the PMS to send over the schematic.

Thanks,
