Notes:
1. Start up time is measured at nominal input and with a constant resistive load.
2. When measuring output ripple, it is recommended that an external 1 µF capacitor and 10 µF capacitor
be connected in parallel from the +V
OUT
to the -V
OUT
pin for single output unis; or from each output to
common for dual output units..
3. Transient recovery is measured to within a 1% error band for a load step change of 25%.
4. Short circuit protection is provided by a “hiccup mode” circuit.
5. Operation at no-load will not damage these units.
6. 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.
For heatsink option, add suffix “H” to model number (i.e.
MI2548S-05RU-H)

An external resister may be added to adjust the converter
output on single output units.
To adjust the output UP, connect a 5%, 3W resistor
between the minus output pin (5) and the Vout trim
pin (6). To adjust the output DOWN, connect a 5%, 3W
resistor between the plus output pin (4) and the Vout
trim pin (6).
The trim table at left gives suggested resistor values
for this adjustment.
