I´m looking for a Integrated DC/DC converter with two diferents outputs, Positive and Inverter output for a +5V / -5V system
someone knows if texas have a circuit like this?
Go through the Power Management Guide to see if they have one.
In reply to sanchayan maity:
I did it but i didn´t find anything. ;)
In reply to lmhynox:
i need something like that
TPS65124 might work if the power levels are low enough on the negative rail.
TPS65130 will work but is over kill.
TPS61040 Figure 19 shows a boost with discrete, unregulated negative charge pump. As long as the currents pulled from each rail track each other (i.e., are close in magnitude), then the regulation on the negative rail should be acceptable.
