Texas Instruments LM5155 | Demoboard PMP22151
70-W flyback and 37-W boost power tree reference design
Details
| Topologie | Sperrwandler |
| Eingangsspannung | 18-29 V |
| Ausgang 1 | 28 V / 2.5 A |
| IC-Revision | B |
Beschreibung
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.
Eigenschaften
- High efficiency flyback and boost power stage
- Compact size (2" x 3.75") minimizes solution size area
- Single-side assembly and 2-layer PCB for reduced manufacturing costs
Typische Anwendungen
- Fire alarm control panel (FACP)
