Start up time is measured at nominal input and with a constant resistive load. 2. Cross regulation is measured with the output being tested at 50% load. The second output is varied from 10% to 100% load. 3. 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. 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. Isolation capacitance for 24 VDC output models is 2,000 pF. Isolation capacitance is measured from input to output at 100 kHz/0.1V. 7. The maximum control current at the on/off pin (pin 6) during a logic high is 50 µA. The maximum control current to the on/off pin at logic low (-0.7V to 0.8V) is 1 mA. If the on/off pin is left open, the unit operates. If it is grounded, the unit will shut off. 8. 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. 9. These units should not be operated over +85°C. Exceeding +85°C may damage the unit. 10. 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. Derating Curve 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: Trim UP = RTRIM = A $-R2 - R3 R2 A Trim Down = RTRIM = A $-R1 - R3 R1 A Where A = VREF $ R1 VTRIM - VREF Where A = VTRIM VREF $ R2 VREF Where RTRIM = The value of the external trim resistor VTRIM = The amount of voltage adjustment required The value of R1, R2, R3 and VREF are given in the table below.
