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)
