2 Watt DC/DC Power Converters
NOTES
1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C.
MIL-HDBK-217F Notice2 @Ta=25°C, Full load (Ground, Benign, controlled environment).
2. Maximum value at nominal input voltage and full load.
3. Typical value at nominal input voltage and no load.
4. Typical value at nominal input voltage and full load.
5. Test by minimum Vin and constant resistive load.
6. The RGUW2 series meets EN55022 Class A and input reflected ripple current with an external L-C filter before the input pins to the
converter. (See Class B figure for connecting network)
Recommended: 12Vin: C1=10µF/25V 1812 MLCC C3=220pF/3KV 1808 MLCC L1=2.2µH 0504 SMD Inductor P/N: PMT-059
24Vin: C1=6.8µF/50V 1812 MLCC C3=220pF/3KV 1808 MLCC L1=18µH 0504 SMD Inductor P/N: PMT-046
48Vin: C1=4.7µF/100V 1812 MLCC C3=220pF/3KV 1808 MLCC L1=18µH 0504 SMD Inductor P/N: PMT-046
7. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor suggested is
Nippon chemi-con KY series, 220μF /100V, ESR 48mΩ.
8. To order surface mount version, add the suffix “S” to the model number (Ex: RG24S5UW2S).
9. To order 3000VDC I/O isolation version, add the suffix “H” to the model number (Ex: RG24S5UW2H).
10. CAUTION: Internal fusing is not included so we suggest using an input line fuse.
