When measuring output ripple, it is recommended that an external 0.47 µF ceramic capacitor be placed from the +Vout pin to the -Vout pin for single output units and from each output to common for dual output units. For noise sensitive applications, the use of 3.3 µF capacitors will reduce the output ripple. 2. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%. 3. No-load operation will not damage these units, however, they may not meet specifica- tions. 4. Dual output units may provide a 10V, 24V or 30V output. To do this, connect the load across the positive (+Vout) and negative (-Vout) outputs and float the output common. 5. 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 (ESR <1.0Ω at 100 kHz) capacitor be mounted close to the converter. For 24V input units a 4.7 µF is recommended, and for 48V units a 2.2 µF. 6. Maximum capacitive load for single output units is 3,000 µF, for dual output models it is 180 µF for each output. 7. 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. Remote ON/OFF Notes: 1. Maximum sink current at the on/off pin (pin 1) during a logic low is 300 µA. 2. Maximum allowable leakage current of a switch connected to the on/off terminal (Pin 1) at logic high (2.5V to 100V) is 200 µA. Parameter Condition Units Supply On 2.5 to 5.5 or Open Circuit VDC Supply Off -0.7 to 0.8 VDC Standby Input Current 10 mA Control Common Referenced to Negative Input (-Vin) Remote ON/OFF Notes: • All dimensions are typical in inches (mm) • Tolerance x.xx = ±0.01 (±0.25) • Pin 1 is marked by a “dot” or indentation on the unit |
