Notes:
1. Start up time is measured at nominal input and with a constant resistive load.
For heatsink option, add suffix “H” to model number (i.e.
MI2512S-05RW-H)
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.

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 right gives suggested resistor values for
this adjustment.
