DANUBE http://www.danube.com.tw 6 2014/04/28 NU SERIES APPLICATION NOTES: EXTERNAL CAPACITANCE REQUIREMENTS: Output filtering is required for operation. A minimum of 10uF is needed. Output capacitance may be increased for additional filtering, not to exceed 220uF. To meet the reflected ripple requirements of the converter, an input impedance of less than 0.5 ohm from DC to 250KHz is required. We Can Offer EMC-Filter According To EN55011/22 Class B. Negative Outputs: A negative output voltage may be obtained by connecting the +OUT to circuit ground and connecting –OUT as the negative output. FOR MORE INFORMATION CALL: Danube Enterprise Co., Ltd.
