Hi Xuan,

thanks for using the e2e forum.

Can you give more information on the application?
E.g. Topology, input range, output voltage, output power

Does it need to be a Buck-Boost or a Boost with bypass?

It is possible to filter the TI portfolio for devices with a max duty cycle of 100%:

Best regards,
Niklas
