Your power supply needs to able to provide current bursts upwards of 1A. There are many threads here which discuss buck converters. Have you looked at the list of Similar Threads below?

It has special pin FBO which enables to parallel the outputs. Or this app note has way to increase the input voltage of any BUCK or LDO. https://www.ti.com/lit/an/slva119/slva119.pdf Power integrations (powerint.com) have few families like TinySwitch or TOP switch with MOSFET's with very high voltage capability. I am not sure whether we can use them as buck. Check with applications team
