How to generate positive and negative power supplies from a single supply with high current driving capability?
MIL-STD-1553B


1Mbps Bi-Phase HDX on a 1:1.41 ratio transfomer isolated Twin-Ax bus
Tx Vout= 18–27 Vpp
Twin-Ax is 78 Ohms (60~85) 
Tx/Rx side has 58 Ohms on each leg. (=0.75 Zo) 


It is possible to use a single or bipolar but lower current losses occur with bipolar supply.

There are several ways to generate with boost from 3V to +/- 14V You will need about 5W with 50% duty cycle.

The CT3231M is one such ASIC method but not cheap.


GJV289A is the Chinese equivalent of MIL-STD-1553.

Designing the supply requirements comes only after the precise design specs are given for environment, voltage, current, temp rise, ripple, cost etc.**
