Hi everyone,
I've been trying to work on a design for a decent lab low power lab power supply, since I do not currently own one. Which method I take has jumped from linear to SMPS, current limited or not current limited, high power or low power....However, I've pretty much determined that I all I really want is a decent low-ish power supply capable of 1A/rail and with an adjustable output.
So I'm back on the SMPS track, but the biggest thing I have an issue with is that I do not know what a good negative switching part would be. Sure there is inverting stuff, but I don't need that since my bridge rectifier would be able to supply both positive and negative DC. I'd like to use matching parts for the + and - rail.
I've been looking at a wide variety of parts ranging from LM2575 to MC34063 and I just do not know how to go about. Granted, I could probably get away with a linear regulator on the negative rail because I'd probably hardly use it anyway, but for the sake of being professional and me being picky, I'd like to try switchmode there as well.
I don't know a whole lot about switchmode design internally, so I don't really know the dos and don'ts.
But, I would appreciate any input.
Thanks.
