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 2). R= 3 R Vi n Vc-VD-1.0 Ic 2 6 + Vo N Lin 8 Cin Cout Cs 1 GND 7 0V 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. IS C 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) D Figure 2 4. Input Current(A) 2. O CS Pin-By connecting a low ESR capacitor between this terminal and the pin-7 (Figure 1). the output ripple and noise may be further improved. Generally, the capacitance is no greater than 47uF. 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.
