ASM51

Hello sirs.
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)

Recommendations?

This power supply will be used in supersonic applications. Help?

I used the LT1615 once to boost a pair of NiMH batteries to 10V ad it worked very well, the datasheet is full of examples, and I highly suggest it.
