I am trying to create a circuit to generate the boost voltage for mosfet highside driving. Instead of using gate drivers or individual boost circuits for for each highside mosfet I want to create one centralized boost power supply. This is because there are 30 half bridges on the board.
I was thinking of using an LM5022 to create the boost voltage. However I want the boost voltage to be about +10 above VP. The LM5022 will output a fixed voltage which is no good for this application because the VP voltage will change over a large range. I think there must be a way of configuring the LM5022 to be some voltage above the input voltage. Its a bit beyond my knowledge so I thought I would seek some help.
Thanks!
