Detector of buck converter controller

[azadfalah]

Hello friends

The IC controller in the image is a bit similar to MC34063, but there is a difference in the pin. Does anyone know the part number of this IC?

The module seller says that this module can withstand 72 volts of input

Thanks

The high voltage can be do to the circuit or IC. As you know the ICs maximum voltage can be extended to higher levels with external components. The LM2596 high voltage version can withstand 57V.
