To meet the reflected ripple requirements of the converter, an input impedance of less than 0.5 ohm from DC to 100KHz is required. External output capacitance is not required for operation, however it is recommended that 10uF tantalum and 0.1uF ceramic capacitance be selected for reduced system noise. Additional output capacitance may be added for increased filtering, but should not exceed 220uF. www.Power-Systems.de Page: 5 / 6 Version: 4-Oct-02 DC-DC Converter UNIT LW Series ( 5 W WIDE INPUT RANGE DC-DC CONVERTER ) Negative Outputs: A negative output voltage may be obtained by connecting the +OUT to circuit ground and connecting –OUT as the negative output.
