    Hi Kevin,

    TI has not released Class-AB amps in some considerable time. There are a few options that you may consider in this link. Here some additional notes:

    • LM devices are in TO-263 package only
    • LM1877 does not seem to fit in this application, output power is lower than requirement

    Can customer be able to consider Class-D amps? LC filter can be used if there is EMI constraint on the applicaiton.

    Best regards,
