APPLICATION

NOTE

SIZE Graph

1) Recommended circuit

If you want to further decrease the input/output ripple, an ”LC” filtering network may be connected to the input and output

ends of the DC/DC converter, see (Figure 1). 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.)

Lin:

4.7PH ~120PH

Lout:

2.2PH ~10PH

2) Input current

While using unstable power source, please ensure the output voltage and ripple voltage do not exceed indexes of the

converter. The preceding power source must be able to provide for converter sufficient starting current Ip.

General: Ip≤1.4*Iin-max

3) No parallel connection or plug and play
