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 should be equipped as close as possible to the input terminals of the TEN 60 converter for lower impedance. Output Over Current Protection When excessive output currents occur in the system, circuit protection is required on all converers. Normally, overload current is maintained at approximately 150 percent of rated current for TEN 60 series. Hiccup-mode is a method of operation in a converter whose purpose is to protect the power supply from being damaged during an over-current fault condition. It also enables the converter to restart when the fault is removed. One of the problems resulting from over current is that excessive heat may be generated in the TEN 60 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. Output Over Voltage Protection The output over-voltage protection consists of a Zener diode that monitors the output voltage on the feedback loop. If the voltage on the output terminals exceeds the over-voltage protection threshold, then the Zener diode will send a current signal to the control IC to limiting the output voltage. Thermal Consideration The TEN 60 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 110°C. When operating, adequate cooling must be provided to maintain the test point temperature at or below 110°C. Although the maximum point temperature of the power modules is 110°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 to to turn on and off the TEN 60 converter; the user must use a switch to control the logic voltage high or low level of the pin referenced to -Vin. The switch can be open collector transistor, FET and Photo-Couple. The switch must be capable of sinking up to 1 mA at low-level logic voltage. High-level logic of the ON/OFF signal maximum voltage is allowable. Leakage current of the switch at 15V is 50 µA.

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 set point increases. With an external resistor between the TRIM and SENSE(+) pin, the output voltage set point decreases.

The Remote Sense voltage range cannot be over 10% Vout, i.e.: [+Vout to -Vout] – [+Sense to -Sense] ≦ 10% Vout If the Remote Sense function is not used, then the +SENSE has to be connected to +Vout and the -SENSE has to be connected to -Vout.

An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of sophisticated power architecture. To 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 5A for TEN 60-24xx modules and 3A for TEN 60-48xx 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 60 series of DC/DC converters has been calculated using Bellcore TR-NWT-000332 Case I: 50% stress, Operating temperature at 40°C (Ground fixed and controlled 6 environment ). The MTBF is: 1.093×10 hours. MIL-HDBK 217F NOTICE2 FULL LOAD, Operating temperature at 25°C. The MTBF is: 1.096×105 hours.
