UL-60950-1 Certified
Description
The E-Series of DC/DC Converters are fully certified to EN 60950: 2000.
The E-series of these DC/DC-converters is designed to meet UL 60950. This makes them ideal for all
telecom and safety applications where approved isolation is required. They are also designed to meet
UL 1950 and CSA 950 standards (10).

Notes :
1. The RP20 series requires a minimum of 10% loading on the output to maintain specified regulation. Operation under
no-load condition will not damage these devices, however they may not meet all listed specification.
2. BELLCORE TR-NWT-000332. Case l: 50% Stress, Temperature at 40°C (Ground fixed and controlled environment).
3. Simulated source impedance of 12µH. 12µH inductor in series with +Vin.
4. Maximum value at nominal input voltage and full load of standard type.
5. Typical value at nominal input voltage and full load.
6. Test by minimum Vin and constant resistor load.
7. The ON/OFF control voltage is reference to negative input.
8. Heat sink is optional and P/N: 7G-0011A. Operation temperature range please see curve.
9. Cross regulation:
Dual output—Asymmetrical load 25% to 100% full load
Triple output – 3.3V / 5V 100% load and one of auxiliary 100% load, other auxiliary load change from 25% to 100% load
10.See application notes for EMI-filtering.
