Part Number: TPS61099

Hi,

We have a question about load transient response of TPS61099 from our customer.

When changing from no-load to 30 mA,It takes 250μsec to stabilize the output voltage.

■Conditions: Vin=2.0V,Vout=3.0V,Iout=10-30mA,Prototype board

■Question
Is there any way to improve load transient response under light load（Iout=10-30mA)?

Best regards,
Seishin

could you share the waveform you observed? you can also add 10pF feed-forward capacitor to improve the response.

Dear Jasper Li,

Thank you for your quick response.

I want to send you the waveform from the customer, but that file is our customer NDA.

How can I contact you in this case?

Best regards,
Seishin
