Highly inductive source impedance can affect the stability of the power module. Input external L-C filter is recommended to minimize input reflected ripple current. The inductor is simulated source impedance of 12µH and capacitor is Nippon chemi-con KZE series 47µF/100V. The capacitor must as close as possible to the input terminals of the power module for lower impedance. Output Over Current Protection When excessive output currents occur in the system, circuit protection is required on all converters. Normally, overload current is maintained at approximately 150 percent of rated output current . Hiccup-mode is a method of operation in a converter whose purpose is to protect the converter from being damaged during an over-current fault condition. It also enables the converter to restart after the fault is removed. One of the problems resulting from over current is that excessive heat may be generated in the converter; especially MOSFET and Schottky diodes and the temperature of those devices may exceed their specified limits. A protection mechanism has to be used to prevent those power devices from being damaged due to over heating. Output Over Voltage Protection The output over-voltage protection consists of output Zener diode that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over-voltage protection threshold, then the Zener diode clamps the output voltage. This protection is only available on the TEN 40-WI single output. Thermal Consideration The TEN 40-WI operates in a variety of thermal environments. However, sufficient cooling should be provided to ensure reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the point as shown in the figure below. The temperature at this point should not exceed 105°C. When operating, adequate cooling must be provided to maintain the test point temperature at or below 105°C. Although the maximum point temperature of the power modules is 105°C, you can limit this temperature to a lower value for higher reliability.

Considering space and air-flow is the way to choose which heat-sink is needed. Order Code: TEN-HS3 All dimensions in millimeters Remote ON/OFF Control The Remote ON/OFF Pin is controlled DC/DC power module to turn on and off; the user must use a switch to control the logic voltage high or low level of the pin referenced to -Vin.

This is accomplished by connecting an external resistor between the TRIM pin and either the +SENSE or -SENSE pins. With an external resistor between the TRIM and -SENSE pin, the output voltage value will increases. With an external resistor between the TRIM and +SENSE pin, the output voltage value will decreases.

An input line fuse must always be used. This encapsulated converter can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of sophisticated power architecture. To keep maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow fuse with maximum rating of 8A for TEN 40-24xxWI modules and 5A for TEN 40-48xxWI modules. Based on the information provided in this data sheet on Inrush energy and maximum DC input current; the same type of fuse with lower rating can be used. Refer to the fuse manufacturer’s data for further information. MTBF and Reliability The MTBF of TEN 40-WI DC/DC converters has been calculated according to: • Bellcore TR-NWT-000332 Case I: 50% stress, Operating Temperature at 40°C (Ground fixed and controlled environment ). The resulting 6 figure for MTBF is: 1.105×10 hours. • 5 MIL-HDBK 217F NOTICE2 FULL LOAD, Operating Temperature at 25°C. The resulting figure for MTBF is: 1.511×10 hours.
