>>934645 nigga if you can't figure out a linear datasheet theres not much hope for you.
easiest way without doing any math will be to attach a 100k pot across the output rail with the wiper going to VFB, you can then just turn it until the right voltage comes out, make sure you start low(towards negative) or you'll likely damage the controller as soon as Vout > Vin.
>>934645 Put a 3:1 transformer in between the mosfets and the filter caps. If the switching speed is very high, you can probably wind the transformer yourself. Above 50kHz or so, you only need a couple dozen turns on a decently large toroidal core. If the max current output is 10A like >>934731 says, you can use higher rated mosfets or put several in parallel. If you go parallel you'll have to include some gate resistors and/or a driver circuit to make sure they all turn on and off together.
Needless to say, this is adding a lot of pointless complexity when you can just find something that is rated for what you want.
>>935309 What are you trying to power? 60 amps is no easy feat, it will require a very tight layout.
Literally everything is going to be a power resistor at those currents. Suffice to say you are going to need paralleled MOSFET's, large inductors rated for at least 150amp amp peak currents and capacitors in parallel to spread out the ripple currents.
>>935309 Then you shouldn't be trying to design such a complicated power supply. People go to university for years to learn how to do this. Just go on digikey or some other electronics wholesaler and look under voltage regulators for something that fits your needs, then follow the schematic in the datasheet EXACTLY.
>>935341 If you're referring to the picture in the OP, it's a schematic for a power supply that doesn't meet the specified requirements. Don't try to re-engineer something if you don't know what you're doing; just find something that does what you want to begin with.
>>935354 You would probably have to use smaller inductors to keep the duty cycle from maxing out, something like 6.8uH I assume.
The whole diagram is really just an example, each MOSFET would need a gate resistor and the thing that dictates that is the circuit layout as the parasitic inductance forms an LC circuit with the gate capacitance, things like this can cause oscillations and popped MOSFET's in less than a microsecond.
