DBW

The DBW series of DC/DC converters offers 40 Watts of output power in a 2 x 2 x 0.4 inch package. The DBW series has a 4:1 ultra wide input range of 9-36VDC or 18-75VDC. This series also offers single and dual output models. Some features include 1600VDC isolation, positive or negative remote on/off, and six-sided shielding. All models are short circuit, over voltage, over load, and over temperature protected. Heatsinks are also available, please call factory for ordering details

Notes & safety
Notes: 1. MTBF: BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40°C. MIL-STD-217F Notice2 @
Ta=25°C, Full Load (Ground, Benign, controlled environment).
2. The output requires a minimum loading on the output to maintain specified regulations. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications.
3. For single output models: maximum output deviation is 10% inclusive of remote sense and trim. If remote sense is not being used the +SENSE should be connected to the +OUTPUT and the -SENSE should be connected to the -OUTPUT.
4. Load regulation for dual output: Minimum load to 100% load balanced on all outputs.
5. Cross regulation for dual output: asymmetrical load 25% / 100% full load.
6. The ON/OFF control function: There are positive (standard) and negative logic (option). The pin voltage is referenced to negative input. To order negative logic ON/OFF control add the suffix "R" to the part number (Ex: DBW48S5-40R).
7. Heat sink is optional. Please call factory for ordering details.
8. The DBW series can meet EN55022 Class A with an external capacitor in parallel with the input pins. Recommended: For 24Vin: N/A. For 48Vin: 2.2uF/100V * 2 PCS 1812 MLCC.
9. 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, 220uF/100V, ESR 48MΩ.
Due to advances in technology, specifications are subject to change without notice.
Safety Approvals: UL60950-1, EN60950-1, IEC60950-1 Licensed
