Notes:
1. Operation at no load will not damage these units. However, they may not
meet all specifications.
2. These converters will operate without external components. However,
when measuring output ripple, it is recommended that an external
ceramic capacitor be placed from the +Vout pin to the -Vout pin for
single output units and from each output to common for dual output
units. An input capacitor will enhance stability over temperature and
input line variations. For applications requiring very low output noise
levels, a simple LC filter, as shown in the connection diagram below,
should be effective. Recommended component values are given in
the table below the diagram.

3. The typical switching frequency for the
MD105D-15ER
is 250 kHz. For the
MD124D-15ER
the typical switching frequency is 300 kHz.
4. It is recommended that a fuse be used on the input of a power supply for
protection. See the Model Selection table above for the correct rating.
