Note:

1. Tested at input voltage range and full load.

2. At 0~100% load, the max load regulation is ±5%.

3. Unbalanced loads should not exceed ±5%. If ±5% is exceeded, the product performance cannot be guaranteed.

4. Value is based on full load. At loads <50%, the switching frequency decreases with decreasing load.
