3D8W4_1.6RP series
3Watt - 4:1 Regulated Single & Dual output
DC-DC Converter
3 Watt
The 3D8W4_1.6RP series is a family of cost effective and high performanced
3W single & dual output DC-DC converters. These converters are built in non-
conductive black plastic package in a 8-pin DIL miniature compact case with high
performance features wide range devices operate over 4:1 input voltage range
providing stable output voltage. Devices are encapsulated using flame retardant
resin. Input voltages of 12, 24, 48 Vdc with output voltage of 3.3, 5, 12, 15, 5, 12,
15 Vdc. High performance features include high efficiency operation up to 84%
and output voltage accuracy of 1% maꢀimum.

Note:
1. One load is 25% to 100% load, the other load is 100% load, the output voltage
variable rate is within 5%.
2. Ripple/Noise measured with a 10μF electrolytic capacitor and 0.1μF ceramic
capacitor.
3. Test by minimal Vin and constant resistive load.

4. Test by normal Vin and 100%-25% load,25% Ioad step change.
5. Measured Input reflected ripple current with a simulated source inductance of
27μH and a source capacitor Cin (47μF, ESR<1.0Ω .

6. “Nature Convection“ is usually about 30-65 LFM but is not equal to still
air (0 LFM).
7. Eꢀceeding the absolute ratings of the unit could cause damage. It‘s not allowed
for continuous operating ratings.
8. Input filter components are required to help meet conducted emission class A,
Which application refer to the EMI Filter(Conduct ).
9. An eꢀternal filter capacitor is required if the module has to meet IEC61000-4-4
and IEC61000-4-5. The filter capacitor Motien suggest: Nippon - chemi - con KY
series, 220μF/100V.
