LMZM23600: Is LMZM23600 able to convert 24V(max 28V) to -10V?

Hi team,

My customer is seeking a power module to convert 24V(typical) to ±10V，and the maximum Vin voltage is 28V, load current need 250mA.

Is those 4~36Vin buck module like LMZM23600, LMZM33602 able to guarantee the IC performance when the Vin of power module is larger than 36V but less than 42V(the absolute maxim voltage of LMZM23600/33602)?

For example, when use as BUCK-BOOST topology, and input =28V/ output= -10V, means the module Vin will be 38V,  can LMZM23600/LMZM33602 still guarantee its performance?

If not, can you give some power module recommendation for 24Vtypical/28Vmax Vin, +10/-10V Vout, 250mA application?

Thank you
