Hi AllAboutCircuits,
I'm designing a board at work with some constraints that has me stumped.
I need to supply several voltages, but only have 6 connectors for power that can go into an oven for burn-in. I have another smaller 72-pin connector but that's used for some logic and data signals:
Here are the several power supplies I need:
[] +150 V
[] -150 V
[] +138 V
[] -138 V
[] -6 V
[] 6.5 V
[] 5.5 V
[] 3.3 V
I was brainstorming whether I can 'split' some of the smaller power supplies from one of the smaller supplies... using either Zener diodes or linear voltage regulators. Not sure how to implement it though. Should I use a multiple linear voltage regulator?
I searched through some of these links and forums for some insight:
Can I obtain a new voltage source from outputs of two cascaded linear voltage regulators in practice?
Power Supply Design - Multiple Voltage Regulators
The section I'm referring to is on number '6.'
Supplying 5.5 V and 3.3 V from a 6.5 V supply
Thanks
