Hi. I have a 24v/5A DC output. I want to get +10V/0.7A, -10v/0.7A, +5v/1A and +3.3V/2A DC o/p from this. What kind of voltage regulators can I use? Any reference designs for these outputs?
Theoretically possible to generate all form one flyback.
But I´d use sing SMPS.
For sure it depends on your needs: cost, volume, size, isolation, EMI noise, voltage riple, voltage accuracy, efficiency....

Reference designs:
Every SMPS manufacturer as well as every SMPS IC manufacturer provides additional information like: datasheets, application notes, design notes, reference designs... and so on.

Reliability, many considerations, like if one supply fails do you want the
others to run, more components = less reliability (in general), this is a
topic in its own right.
I need to design a power supply that is powered from a single Li-ion cell (3-4.2V) and provides 3.3V up to 500mA and 5V up to 1A. I have three solutions in mind, one is boost converter to 5V and th...
In the interest of "just getting it done, cheap" I'd look for a generic "28V" to split 15V + 5V brick (or smaller module) and a 5V to 3.3V POL buck. Presuming no great sequencing issues etc.
By applying your 24VDC supply across a stack of 2 capacitors, you get split 12V supplies. Designate a new ground between them and call one positive and the other negative. Add a half-bridge to give more current to the upper capacitor so as to compensate for its greater amount of loads.
By putting an inductor where a wire was, it smoothes waveforms which are otherwise spike-y with peaks of several Amperes through the capacitors.
