NOTES
1. Measured with 1uF ceramic capacitor connect to the output pins.
2. Measured from high line to low line.
3. Measured from full load to 10% load, dual outputs loaded equally.
4. Output Power
100%.

(°C)
5. The converter required a minimum 10% loading on the output.
Operation below 10% load conditions will not damage these
devices. However they may not meet all listed spec.
6. Recommended Reflow Soldering
