Derating Curve  
1. The specified maximum capacitive load is for each output.  
2. Start up time is measured at nominal input and with a constant resistive load.  
3. Cross regulation is measured with the main output set at 50% load.The second output is varied  
from 10% to 100% load.  
4. When measuring output ripple, it is recommended that an external ceramic capacitor (approx  
1 µF to 10 µF) be placed from the +VOUT to the -VOUT pins.  
5. Transient recovery is measured to within a 1% error band for a load step change of 25%.  
6. Short circuit protection is provided by a “hiccup mode” circuit.  
7. Isolation capacitance for 24 VDC output models is 2,000 pF. Isolation capacitance is measured  
from input to output at 100 kHz/0.1V.  
8. The control input (pin 6) is referenced to the -VIN (pin 2) input. If it is grounded, the unit will  
shut off.  
9. These units should not be operated with a load under 10% of full load. Operation at no-load will  
not damage the unit, but they may not meet all specifications.  
10. These units should not be operated over +85°C. Exceeding +85°C may damage the unit.  
11. 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.  
External Trim  
External Trim Notes:  
On single output units, an external resistor can be used to adjust the converter  
output up/down by about 10%. The connection is shown in the diagram at left. The  
required resistor value is calculated by the formulas:
