MC34063A... alternative?

Hello everyone!


I've been using until now the MC34063AD to step down the voltage from 28 to 5V, consuming an output current of 0.8A.
But now, I need to replace this component for another capable of supplying a minimum of 1.9A to your departure.


First of all, I don´t want to use any of: LM3485, LM3489, because I don´t want a controller because I want a component to has a integrated MOSFET.
Any suggestions or ideas?


I've been watching the TPS54331DR, TPS54233 but they maximum input voltage is of 28V ... :( something like I´m looking for? Without a lot of money going ...
Thanks to all :)
