- 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.
- Regulation
With a semi-regulated design, the converter’s output
voltage varies with load current and will change
proportionally to the input voltage. If regulated
output is needed, an external regulator can be used
as shown in Figure 2.
Table 1

External Input Capacitance
- 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.

- Output filtering
- External Regulator
An output capacitor is needed to meet output ripple
requirements as shown in Table 2.
An external 3-terminal regulator can be connected
to the output of the converter to achieve full
regulation. Make sure the converter’s output voltage
provides sufficient head room for the regulator. An
additional benefit is that the built-in protection
features in the regulator, such as OCP, OTP, etc, will
protect the converter also. In a complimentory
supply, a negative output regulator must be used to
achieve the negative regulated output.
Output capacitance may be increased for additional
filtering, but should not exeed 10µF or expanded to
an LC network as in Figure 1.
