DANUBE http://www.danube.com.tw 7 2016/03/11 KQWS SERIES APPLICATION NOTES: EXTERNAL CAPACITANCE REQUIREMENTS: External output capacitance is not required for operation, however it is recommended that 10uF MLCC and 0.1uF ceramic capacitance be selected for reduced system noise. Additional output capacitance may be added for increased filtering, but should not exceed 1000uF. Negative Outputs: A negative output voltage may be obtained by connecting the +OUT to circuit 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 t his 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% 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.
