Hi
I'm supposed to build a buck type interleaved converter with specs roughly 100V input 36 V output with total power near kW level. I could not find a controller IC aimed for this kind of converter.
TPS4009 seems a very good solution however it is specifically written in its datasheet that this product aims low power high current applications.
How come a controller dictate input output voltage levels and power of a converter? Its duty is mainly create an error signal, amplify it accordingliy and produce duty cylce, isn't it? Or, are the voltage values i see recommended for IC supply, i.e can i use this controller in a higher rating converter with an auxillary converter dedicated for feeding IC? Will it be okay if i take the output voltage information with a divider then feed it to the IC? Or, is there any other solution?
I appreciate any comment or help
Thank you
