Typical application Input and/or output ripple can be further reduced, by connecting a filter capacitor from the input and/or output terminals to ground as shown in Fig.3. Choosing suitable filter capacitor values is very important for a smooth operation of the modules, particularly to avoid start-up problems caused by capacitor values that are too high. For recommended input and output capacitor values refer to Table 1. 2021.02.07-A/1 Page 3 of 5 MORNSUN Guangzhou Science & Technology Co., Ltd. reserves the copyright and right of final interpretation DC/DC Converter A_XT-1WR3 Series Vin GND Cin DC DC Cout Cout Fig.3 2.
