DC/DC ConverterU/VRB_J(M)T/D-3W & VRA_JMD-3W Series Efficiency Vs Output Load(Vin=5V) 100 r Design Reference 1. Typical application All the DC-DC converters of this series are tested before delivery using the recommended circuit shown in Fig. 2. 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 max. capacitive load value of the product. MORNSUN GUANGZHOU SCIENCE & TECHNOLOGY CO..LTD....
