Other Parts Discussed in Thread: TLV62569

Hi Team,

There is a special condition for customer as below.

input = 5V

output = 3.3V/60mA(in long time)

But system sometimes will have 2A current for a moment(10ms) for a moment, but customer wouldn't like to choose 2A solution due to cost.

Do we have corresponding solution for this condition?

Regards,

Roy

    Hi Roy,

    Thanks for reaching out. Do we have more information regarding target efficiency, output ripple requirement?

    Can you also share what is the target price for the customer? Please have a look at TLV62569, our cost optimized 2A buck converter. 

    Looking forward to your reply.

    Thanks and Regards,
    Zain

    Hello Roy,

    We haven't heard back from you. Do you have any further questions here?

    Also here, in terms of reliability of operation even if  a 2A current pulse less than 10 ms will take place. Device needs to be able to handle this without triggering overcurrent limit.

    As Zain mentionned, the TLV62569 is the part we recommend you for tis application.

    Thanks a lot!

    Regards,

    Dorian
