Hello,
I have a project where i currently have 3 pcb's and they all have their own 12V and 5V SMPS running from 24Vdc connection to all, built using National's simple switcher. Now i have the need to generate a +/- 10V analog signal using a 0-5vdc ouput from the uC from one board which will require a minimum of +/- 10 Vdc if i use a rail to rail op amp but would prefer 12V (head room), and power a 3 V ic on another. I am almost out of room on the pcbs and was wondering what the best way to get the added voltages was. to summarize, i need:
Board 1: 12 V, 1.5A, 5 V .5 A
Board 2: 5V .5A, 3V .5A
Board 3: 5V .5A, +/-12 V .5A
Tried nationals Webbench, they seem to use all custom transformers, which i do not even want to mess with. (I like digikey!!!)
