  • Hello Abhinay,

    The MC34063 is a second sourced device originally from Motorola (On Semi) and also made by TI and National Semiconductor (Now known as TI-SVA).  This part can be used in several topologies with up to 40V input.  There are very few other devices which allow the choice of several topologies. If you could tell us which topology you need with 50V input I could make a more clear recommendation.   Vin range Vout and Iout and chosen topology.  Are you using this as a controller or a standalone regulator?

    Off hand;  the LM2594HV 0.5A Buck (or LM2597HV.)  Maybe LM5001MA for Boost and flyback applications.
