The 10-W EW single output series of dc/dc converters target applications requiring input to output isolation. The converters offer input ranges from 9 to 18 V, 18 to 36 V, and 36 to 75 Vdc. The output voltage options are 2.5, 3.3, 5, 12, and 15 Vdc. The input to output isolation is 1,500 Vdc.
The dc/dc converter is housed in a five-sided shielded metal enclosure and features a 1.25 x 0.80 x 0.4-in. case size. All models are fully encapsulated for improved thermal performance. The operating temperature range is –40° to 90°C. The switching frequency of all models is 400 kHz with efficiencies as high as 87%. Output noise is as low as 50 mVp-p. Output voltage accuracy is ±0.6%. Line and load regulation is ±0.3% and ±0.5%, respectively. Temperature coefficient is ±3%, and all models are protected though continuous short-circuit protection.
