The specified maximum capacitive load is for each output. 2. When measuring output ripple, it is recommended that an external 0.47 µF ceramic capacitor be placed from +VOUT to -VOUT for single output models or from each output to common for dual output models. For noise sensitive applications, the use of 3.3 µF capacitors will reduce the output ripple. 3. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%. 4. The maximum control current at the on/off input (pin 2) during a logic high (+5V) is 400 µA. The maximum control current to the on/off pin at logic low (0V) is -400 µA. If the on/off pin is left open, the unit operates. If grounded, the unit will shut off. 5. The recommended reflow settings are a peak temperature of 245 °C for a maximum period (TPK) of 10S and a time above liquidous (TL) of <60 Output Voltage Current Current (VDC) (mA, Max) (mA, Min) 3.3 5.0 12.0 15.0 24.0 ±5.0 ±12.0 ±15.0 3.3 5.0 12.0 15.0 24.0 ±5.0 ±12.0 ±15.0 600 600 250 200 125 ±300 ±125 ±100 600 600 250 200 125 ±300 ±125 ±100 Output Rating Efficiency Capacitive Fuse Slow-Blow (%, Typ) Load (mA) (µF, Max) 90 90 38 30 19 ±45 ±19 ±15 90 90 38 30 19 ±45 ±19 ±15 75 78 80 80 80 77 80 80 75 78 80 80 80 77 80 80 800 800 800 800 800 800 800 800 400 400 400 400 400 400 400 400 220 220 47 47 47 47 47 47 220 220 47 47 47 47 47 47 Derating Curve, 3.3V & 5V Outputs seconds at 217 °C. For more information, please contact the factory. 6. Operation at no-load will not damage these units. However, they may not meet all specifications. 7. The converter should be connected to a low ac-impedance source. An input source with a highly inductive impedance may affect the stability of the converter. In applications where the converter output loading is high and input power is supplied over long lines, it may be necessary to use a capacitor on the input to insure start-up. In this case, it is recommended that a low ESR (<1.0 at 100 kHz) capacitor be mounted close to the converter. For 24V input units a 4.7 µF is recommended and for 48V input models, a 2.2 µF. 8. It is recommended that a fuse be used on the input of a power supply for protection. See the table above for the correct rating.
