I'm designing a schematic for a system that will utilize plug-in daughter boards. I'd like to provide the daughter boards with high quality 12V, 5V, 3.3V, and 1.2V, with up to 5A, available via pins on the daughter board connector.
The main board will utilize a 12V power supply.
I'm trying to find a good approach to using one or more voltage regulator chips to accomplish this.
I've noticed the LMZ22005 which appears to fit the bill, but I would need to use several in order to offer the desired voltages.
I'd like to request suggestions for how to best accomplish this. The device will be for RF use, so EMI is highly undesirable. Recommendations for other chips or general caveats will be much appreciated.
I would prefer to use SMT parts and cost is not the major consideration.
