Help designing boost controller
« on: January 30, 2016, 09:30:16 pm »
I have a project that requires a very high power boost controller.

 have found the LTC3787 as a good start.

But I do not know how exactly to get more power out of a circuit with only one LTC3787 (FETS and inductors are cheap, the LTC3787 is not).

I have been told that reducing the inductance value of the inductors to reduce the duty cycle and using more powerful MOSFETs should work, but I do not know exactly how or what mods I need to have done.

The circuit needs to handle a 12V 65A input and a 36V ~20A output (~800 W).

Please help.

I have attached the image of the circuit from the datasheet
 for reference.

Yeah at that sort of current the inductor will be the most expensive component.
