The discrete solution is a simple solution but is limited on output current voltage regulation and stability.
Q 15v split rail from 12v battery.
This approach can be used when bipolar supplies are required from a single supply input provided the load currents are modest.
The positive voltage rail is created by configuring one ltc3388 3 in its standard buck topology while the negative voltage rail is created with a second ltc3388 3 by grounding the v out connection and using the gnd pin as the negative voltage rail.
