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. MB5012S-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 +VOUT to the -VOUT pins.
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. The switching frequency for 24 VDC output models is 285 kHz.
6. Operation at no-load will not damage these units.
7. 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.
