YF/YFW
The YF series of dc/dc converters perform over an ultra-wide input voltage range (2:1 and 4:1), providing indefinite short circuit and overvoltage protection. This design technology provides upt to 20 watts of output power from a 1.60″ x 2.0″ x 0.40″ case. These current mode control forward converters are designed for improved transient response and reduced stress on switching components and do not require external input filtering, making it a preferred source over industry alternatives.

| Notes: | 1. MTBF:BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40°C. (Ground fixed and controlled environment). 2. All DC/DC converters should be externally fused on the front end for protection. 3. The output requires a minimum 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. 4. The ON/OFF control pin voltage is referenced to -Vin 5. Heatsink is optional (for operation temperature range please see derating curve). Contact Factory for ordering details. 6. Significant capacitive load on output may inhibit start-up and operation, consult factory. 7. The YF/YFW Series can meet EN55022 Class A with an external capacitor in parallel with the input pins. 8. An external filter capacitor is required if the module has to meet EN61000-4-5. 9. The YF Series is 2:1 wide input range of 9-18VDC, 18-36VDC, and 36-75VDC. The YFW Series is 4:1 ultra wide input range of 9-36VDC and 18-75VDC. 10. Maximum case temperature is 100°C. 11. This product is Listed to applicable standards and requirements by UL. Due to advances in technology, specifications are subject to change without notice. |
