For heatsink option, add suffix “H” to model number (i.e.
MB5024S-03RU-H)
Notes:
1. Start up time is measured at nominal input and with a constant resistive load.
2. Load regulation is specified for a load change of minimum load to full load.
3. 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
pins.
4. Transient recovery is measured to within a 1% error band for a load step change of 25%.
5. Short circuit protection is provided by a “hiccup mode” circuit.
6. Operation at no-load will not damage the unit.
7. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selec-
tion table above for the correct rating.
Remote On/Off
Applying a signal to pin 3 will turn the unit ON/OFF. If the pin is left open, the unit operates. If
grounded, the unit will shut off. The specifications for the ON/OFF function are:

An external resister may be added to adjust the converter
output.
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.
