| Input voltage | 27-29 V |
| Output 1 | 37 V / 1 A |
| IC revision | B |
This reference design uses two LM5155 devices to make a flyback and boost power stage. The flyback creates an isolated 28 Vdc bus from a 24 +/-10% Vdc bus and the boost creates a 37 Vdc bus from the output of the flyback. The flyback can be loaded up to 70 W and the boost can be loaded up to 37-W. All components are placed on one side of the board to reduce assembly complexity and cost. Both power stages achieve over 90% efficiency across output conditions.
