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). NCs 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 2. CTRL Terminal When open or high impedance, the converter will work well; When this pin is ‘high’; the converter will shutdown; It should be noted that the input current should remain between 5-10mA,exceeding the maximum 20mA will cause permanent damage to the converter. 3. 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) TI Ip N Figure 1 Input Current(A) N 1. Input Voltage Range Output Load In order to ensure the product operates efficiently and reliably, make sure the specified range of input voltage is not exceeded. IS C 4.
