NOTE

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

2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1uf & 47uf 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.
