UCC27611: Minimum Pulse Width

Part Number: UCC27611
Other Parts Discussed in Thread: LMG1020

Team,

My customer is asking the UCC27611 has any minimum pulse width requirements for the outputs? This information doesnt seem to be in the datasheet.

Thanks and Regards,

    Hello Mihir,

    You can look into the datasheet of UCC27611 for rise/fall time, and propagation delay for turn on and off for the calculation of minimum pulse width, depending on if you will have inverted or non-inverted input. What is your application and what is the min. pulse width that you are looking for?

    We have recently added LMG1020 in our portfolio and this can help you achieve 1ns on time if this is what you are looking for.

    Thanks and regards,

    Hi Lixing,

    Thanks for getting back to me. This is for a LIDAR application. The customer is also considering the LMG1020.

    The LMG1020 can acheive 1ns minimum pulse width. However, its not clear to me how I can calculate the minimum pulse width for the UCC27611? Is it just T_rise + T_fall?

    Regards,
    Mihir

    Hello Mihir,

    You can use: turn on delay - turn off delay + T_rise + T_fall. But UCC27611 could be difficult for pulse width less than 10ns. LMG1020 could be a much better solution to go.

    Thanks and regards,
