Can TPS40200 handle surge up to 60V?

Any 60V version of TPS40200 to replace LT3824?

    The TPS40200 controller will not support a 60V surge voltage.  The absolute maximum voltage is 52V, anything higher could result in IC damage.

     

    The TPS40060/61 is a similar part, though allowing synchronous rectification.  The TPS40060/61 could drive a non-synchronous power stage since they don't use the low-side FET for current limit or a synchronous power stage for higher efficiency.  The TPS40060 and TPS40061 are 10-55V devices with a 60V absolute maximum.  They will function if the input voltage does not exceed 60V

    If the load current is less than 2.5A, the TPS54260 is a 3.5V to 60V input 2.5A output non-synchronous PWM converter with integrated high-side MOSFET.  This could replace the TL3824 controller in applications less than 2.5A with an integrated FET solution in a thermally enhanced 10pin MSOP pacakage.  The same size as the LT3824, which requires an external MOSFET.

    Check back soon though.  TI is constantly updating their profolio and releasing new devices.  There may be something in the near future.
