notes:

1. Measured from high line to low line at rated load.

2. Measured from full load to 10% load at 115 V ac.

3. Ripple & noise are measured at 20MHz bandwidth with 0.1 µf ceramic & 10 µf electrolytic capacitors on the output.

The two earth ground pads are connected to input earth ground.

4. See derating curves

parameter

conditions/description

output overload

current limiting starts at 105% of the rated output current and recovers automatically

output over voltage output voltage is limited by TVS clamping to: 6.8 V for 3.3 & 5 V models, 135% for all other models

output short circuit protected, long-term short circuit may reduce reliability
