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. 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.
3. Simulated source impedance of 12uH. 12uH inductor in series with +Vin.
4. The ON/OFF control pin voltage is referenced to negative input.
5. BELLCORE TR-NWT-00332. Case l: 50% Stress, Temperature at 40°C. (Ground fixed and controlled environment).
6. Heat sink is optional and P/N: 7G-0011A. Operation temperature range please see curve.
7. Maximum value at nominal input voltage and full load.
8. Typical value at nominal input voltage and full load.
9. The RP20-243.305DE and RP20-483.305DE are safety approval pending.
