FEW SERIES APPLICATION NOTES: EXTERNAL CAPACITANCE REQUIREMENTS: No external capacitance is required for operation of the FEW series. 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. 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 circui t ground and connecting –OUT as the negative output. Remote ON/OFF: The remote ON/OFF pin may be left floating if this function is not use. It is recommended to drive this pin with an open collector arrangement or a relay contact. When the ON/OFF pin is pulled low with respect to the –VIN, the converter is placed in a low power drain state. Output TRIM: The TRIM pin may be used to adjust the output +10% ~ -20% from the nominal setting .this function allows adjustment for voltage drops in the system wiring. If the TRIM function is not required the pin may be left floating. FOR MORE INFORMATION CALL: Danube Enterprise Co., Ltd.
