Typical application If it is required to further reduce input and output ripple, a filter capacitor can be connected to the input and output terminals, see Fig.3. Moreover, choosing suitable filter capacitor is very important , start-up problems may be caused by too large capacitance. To ensured the modules running well, the recommended capacitive load values as shown in Table 1. The simplest device for output voltage regulation, over-voltage and over-current protection is a linear regulator with overheat protection which is connected to the input or output in series (Fig. 4) Vin GND +Vo 0V DC Cin DC Cout Fig.3 Vin GND 0V +Vo DC DC REG REG Fig.4 Recommended capacitive load value table (Table 1) Vin(VDC) Cin(μF) Vo (VDC) Cout(μF) 5 4.7 5 10 It is not recommended to connect any external capacitor when output power is less than 0.5W. |
