To further reduce output ripple, you may increase the external capacitor, choose a capacitor with low ESR, or add external inductor to the circuit as shown above. TI General: Cin: 12V 100μF 24V & 48V 10μF to 47μF Cout:see Table 2 Vout Cout/μF (max) 5V 1000 9V 680 12 V 470 15 V 330 N Table 1 Input current Nominal input voltage range. The input current of the power supply must be sufficient to the startup current (Ip) of the DC/DC module. (Figure 2) IS C Figure 2 3. Input Current(A) O 2. U Figure 1 1. ED -All of the VWRBT3-SMT Series have been tested according to the following recommended testing circuit before leaving the factory. This series should be tested under load (Figure 1). If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance should not be too high(Table 1). Ip Input Voltage Range Input Voltage (V) Output Load In order to ensure the product operates efficiently and reliably, make sure the specified range of input voltage is not exceeded. No parallel connection or plug and play. NC Terminals Unless otherwise specified, NC terminals of all series are used for converter's interior circuit connection, and are not allowed connection of any external circuit.
