(2) Refer to the Application Notes for information of fusing. For inrush current, refer to the specifications above. (3) 33µF capacitor connected between the two “Input” pins. Then insert current sensor in series with 1.0µH inductor between 100µF and the source. The reflected ripple current is measured over a 5 Hz to 20 MHz bandwidth. (current sensor is located between the converter input pin and the 1.0 µH inductor) (4) Optimum performance is obtained when this power supply is operated within the minimum to maximum load specifications. No damage to the module will occur when the output is operated at less than minimum load, however, below minimum load the dynamic response will degrade. Operation below minimum load is not recommended. (5) Load regulation is defined as the output voltage change when changing load current from a maximum to minimum. (6) Load Transient Recovery Time is defined as the time for the output to settle from a 50% to 75% step load change to a 1% error band (rise time of step = 2µs). (7) Load Transient Overshoot is defined as the peak overshoot during a transient as defined in the Note 6 above. (8) Noise is measured per the Application Notes. Output noise is measured with a 10µF tantalum capacitor in parallel with a 0.1µF ceramic capacitor connected across the output pins. Measurement bandwidth is 0-20MHz. (9) When an external ON/OFF switch is used, such as open collector switch, logic high requires the switch to be high-impedance. Switch leakage currents greater than 10µA may be sufficient to trigger the ON/OFF to the logic-low state. 375 Forbes Blvd. Mansfield, MA 02048 Ph: 800-823-8082 % (10) Most switches would be suitable for the logic ON/OFF control. In case there is a problem you can make the following estimations and then leave some margin. When open collector is used for logic high, “Open Circuit Voltage at ON/OFF Pin”, “Output Resistance” and “External Leakage Current Allowed for Logic High” are used to estimate the high impedance requirement of open collector. When switch is used for logic low, “Open Circuit Voltage at ON/ OFF Pin”, “Output Resistance” and “LOW Logic Level” are used to estimate the low impedance requirement of the switch. (11) Thermal impedance is tested with the converter mounted vertically and facing another printed circuit board 1/2 inch away. If converter is mounted horizontally with no obstruction, thermal impedance is approximately 8°C/W. (12) Water Washability - These DC/DC converters are designed to withstand most solder/wash processes. Careful attention should be used when assessing the applicability in your specific manufacturing process. Converters are not hermetically sealed. (13) Torque fasteners into threaded mounting inserts at 12 in.lbs. or less. Greater torque may result in damage to unit and void the warranty. (14) Input impedance on these units needs to be kept to a minimum. The 9-36Vdc DC units need a maximum input impedance of 0.2 Ohms and the 18-75Vdc DC units need a maximum input impedance of 0.8 Ohms. In order to support this requirement, the 9-36Vdc DC units need 25 µF of capacitance (low ESR) for every 1.0 µH of inductance between the power source and the DC/DC converter. The 18-75Vdc DC units need 1.7µF of capacitance (low ESR) for every 1.0 µH of inductance between the power source and the DC/DC converter. Inductance includes all sources and should take into account input power lines.
