Typical application All the DC/DC converters of this series are tested before delivery using the recommended circuit shown in Fig. 3. Input and/or output ripple can be further reduced by appropriately increasing the input & output capacitor values Cin and Cout and/or by selecting capacitors with a low ESR (equivalent series resistance). Also make sure that the capacitance is not exceeding the specified max. capacitive load value of the product. 2018.12.05-A/3 Page 3 of 5 MORNSUN Guangzhou Science & Technology Co., Ltd. reserves the copyright and right of final interpretation DC/DC Converter VRB_LD-30WR3 Series V in DC C in DC + Vo output voltage (VDC) Cout (F) 3.3/5/9 220 0V 12/15/24 100 C out GND Cin (F) 100 Fig. 3 2.
