NOTE

1. All parameters are specified at normal input, rated load, 25°C 70% RH ambient .

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3.Line regulation is measured from low line to high line at rated load.

4.Load regulation is measured from 20% to 100% rated load.

5.Please prevent the converter from operating in overload or short circuit condition for more than 30 seconds.
