Description
This reference design takes a universal Vac input and creates three isolated 15-Vdc outputs. The main output can be loaded up to 1-A and achieves over 86% efficiency. The other isolated 15-V outputs can be loaded to 50-mA. These outputs have linear regulators to keep the voltages within 1% regardless of cross-loading conditions.
Features
- Primary side regulated flyback to create multiple isolated outputs
- Low profile >20mm design
- 3% accuracy on 1-A output, 1% accuracy on 50-mA outputs
