- Minimum loading
Application Notes:
The converter needs a minimum of 10% loading to
maintain output regulation. Operation under no-load
conditions will not cause immediate damages but
may reduce reliability, and cause performance not to
meet specifications.
- Input filtering
To reduce the reflected ripple current and minimize
EMI, especially when the converter input is more
than 2” away from the DC source, it is recommended
to connect a low ESR electrolytic capacitor between
Vin and Gnd. The values suggested are as shown in
Table 1. If additional filtering is required, the
capacitance may be increased, or expanded to an LC
network as shown in Figure 1.
- Protection
The converter has minimal protection against input
over-voltage or output over-load, and may be
permanently damaged if exposed to these conditions.
An input clamping device can be used for input
voltage limiting. An input fuse or an output fuse
can also be used to protect against over-loading.

As fixed input converters, this series can accept
