Beschreibung
This reference design uses LM5022-Q1 to make an isolated 3.3-V output capable of 1.1-A from a 9-V to 15-V input. All components are placed on one side of the board to reduce assembly complexity and cost. A secondary filter reduces the output ripple to under 30-mV peak-to-peak. The design can achieve 80% efficiency across input conditions.
Eigenschaften
- Less than 1% voltage ripple on output
- 80% efficiency across input voltage range
- Compact board design with top side only assembly
- 1.5-kV AC RMS isolation
Typische Anwendungen
- Boost Converters / SEPIC Converters
