    Hi Francis,

    Please check whether TPS61175 can works in customer's application. 

    Regarding the price, please involve marketing for more detailed information.

    Just let me know if you see any concerns. 

    Regards

    Hi Lei,

    Thanks for your reply. From customer's feedback, the Vin voltage stress is not enough.

    He told me that they changed the input condition, which may reach to 40V, so the max Vin is better to 45V. The output voltage is 12V and output power is ~20W.

    Could you please help promote another suitable device here? Or if we cannot meet the newest requirement, what others we can do here to compete TPQ50571Q? Thanks.

    BRs,

    Francis

    Please check again whether LM5157 or LM5157-Q1 can works in customer's application.
