** The TEP 100 series meets EMC characteristics only with external components connected before the input pin to the converter.
If customer only need to meet EN 61000-4-4, EN 61000-4-5, an external input filter capacitor is required. The filter capacitor Tracopower
suggest: Nippon Chemi-con KY series, 220µF/100V, ESR 48mΩ.

Output Voltage Adjustment
Output voltage is adjustable for 10% trim up or -20% trim down of nominal output voltage 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 decreases. With an external resistor between the TRIM and +Sense pin, the output voltage set point
increases. Maximum output deviation is +10% inclusive of remote sense. (Please refer to page 54, remote sense) The value of
external resistor can be obtained by equation or trim table shown in next page.

100W Single Output
Remote Sense
To minimum the effects of distribution losses by regulating the voltage at the Remote Sense pin. The voltage between the
Sense pin and Vout pin must not exceed 10% of Vout. i.e. [+Vout to –Vout] – [+Sense to –Sense] < 10% Vout
The voltage between +Vout and –Vout terminals must not exceed the minimum output over voltage protection threshold. This limit
includes any increase in voltage due to remote-sense compensation and trim function.
If not using the remote-sense feature to regulate the output at the point of load, then connect +Sense to +Vout and –Sense
to –Vout.
Remote Sense circuit configuration
Input Source Impedance
The power module should be connected to a low impedance input source. Highly inductive source impedance can affect the
stability of the power module. Input external π filter is recommended to minimize input reflected ripple current. The inductor is
simulated source impedance of 12µH and capacitor is Nippon Chemi-con KY series 100µF/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 power supplies. Normally, overload
current is maintained at approximately 110~140 percent of rated current for TEP 100 Series.
Hiccup-mode is a method of operation in a power supply whose purpose is to protect the power supply from being damaged
during an over-current fault condition. It also enables the power supply to restart when the fault is removed. There are other
ways of protecting the power supply when it is over-loaded, such as the maximum current limiting or current foldback methods.
One of the problems resulting from over current is that excessive heat may be generated in power devices; especially MOSFET
and Shottky 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.
The operation of hiccup is as follows. When the current sense circuit sees an over-current event, the controller shuts off the
power supply for a given time and then tries to start up the power supply again. If the over-load condition has been removed, the
power supply will start up and operate normally; otherwise, the controller will see another over-current event and shut off the
power supply again, repeating the previous cycle. Hiccup operation has none of the drawbacks of the other two protection
methods, although its circuit is more complicated because it requires a timing circuit. The excess heat due to overload lasts for
only a short duration in the hiccup cycle, hence the junction temperature of the power devices is much lower.
The hiccup operation can be done in various ways. For example, one can start hiccup operation any time an over-current event
is detected; or prohibit hiccup during a designated start-up is usually larger than during normal operation and it is easier for an
over-current event is detected; or prohibit hiccup during a designated start-up interval (usually a few milliseconds). The reason
for the latter operation is that during start-up, the power supply needs to provide extra current to charge up the output capacitor.
Thus the current demand during start-up is usually larger than during normal operation and it is easier for an over-current event
to occur. If the power supply starts to hiccup once there is an over-current, it might never start up successfully. Hiccup mode
protection will give the best protection for a power supply against over current situations, since it will limit the average current to
the load at a low level, so reducing power dissipation and case temperature in the power devices.

Short Circuitry Protection
Continuous, hiccup and auto-recovery mode.
During short circuit, converter still shut down. The average current during this condition will be very low and the device can be
safety in this condition.
Output Over Voltage Protection
The output over-voltage protection consists of circuitry that monitors the voltage on the output terminals. If the voltage on the
output terminals exceeds the over-voltage protection threshold, then the module enter the non-latch hiccup mode.
Over Temperature Protection
Sufficient cooling is needed for the power module and provides more reliable operation of the unit. If a fault condition occurs, the
temperature of the unit will be higher. And will damage the unit. For protecting the power module, the unit includes
over-temperature protection circuit. When the temperature of the case is to the protection threshold, the unit enters “Hiccup”
mode. And it will auto restart when the temperature is down.
Thermal Consideration
The power module operates in a variety of thermal environments. However, sufficient cooling should be provided to help 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 the figure below. The temperature at this location 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 extremely high
reliability.

Safety and Installation Instruction
The TEP 100 Series has built in the protection function of the polarity reverse as the following figure.
Fusing Consideration
Caution: This power module is not internally fused. 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 slow-blow fuse with
maximum rating of 20A for TEP 100-12xx and 10A for TEP 100–24xx and 5A for TEP 100–48xx. 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 TEP 100 SERIES of 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 figure for MTBF is 1’010’000 hours.
MIL-HDBK 217F NOTICE2 FULL LOAD, Operating Temperature at 25°C. The resulting figure for MTBF is 74’160 hours.
