I have a PCB where I have a precision 3.3V power supply with 1A capacity.
I will need another power supply with 12V or 15V or 20V or 24V capable of supplying around 80mA DC, generated from this 3V3 rail.
I will change the PCB layout when needed, and the only power source available to generate the "boost" voltage is the 3.3V rail.
Somebody recomends controller ICs for this purpose?
I have many types and values of inductors here so I just need to get some samples of some controller ICs, to test them in practice.
This power supply can be not insulated (no need of a flyback insulated design).
I can buy the Boost controllers on Digikey.
The parameters are:
3.3V -> 12V (80mA or more, if possible)
3.3V -> 15V (80mA or more, if possible)
3.3V -> 20V (70mA or more, if possible)
3.3V -> 24V (60mA or more, if possible)
This power supply will be used in supersonic applications. Help?
