Lin However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1). General: Cin: 5V,12V 100PF 24V,48V 10uF Cout: 47PF(typ.)

The value of R Can be derived as follows : 3) 3) 3) 3) Input Input Input Input current current current current While using unstable power source, please ensure the output voltage and ripple voltage do not excced indexes of the converter. The preceding power source must be able to provide for converter sufficient starting current Ip (Figure 2).
