Boost converter two different voltages (9v/12v) from 3.7v battery, attach both to battery, or daisy chain off 9v

If you are making generating 9V from 3.7 and generating the 12V from 9V or vice versa, You are wasting some power at first regulator as the power for second regulator also will have to come through ...

Boost converter two different voltages (9v/12v) from 3.7v battery, attach both to battery, or daisy chain off 9v

I would probably boost to 12 volts and, use a buck converter from 12 volts to 9 volts. However, if the 12 volt device current was significantly smaller than the current taken by the 9 volt device, I ...

Is the zeta DC-DC converter topology scalable to 50kW / hundreds of amps?

For this powerful of a converter, you typically don't want to use a standard hard-switching topology. At 50 kW, even 90% efficiency means that you have to dissipate 5 kW of heat! You need to target ...

Variable DC-DC Buck Converter not working

These MOSFETs are all upside down and won't do what you expect them to do: - The problem is, without driving any GPIOs (Q5-Q7 are all off), I measure an output voltage of 11.88V instead of 5V. Yes, ...
