Output Voltage Adjustment
The output voltage is adjustable from 0% to +20% trim up of nominal output voltage by connecting an external resistor between
the TRIM1 and TRIM2 pins. With an external resistor between the TRIM1 and TRIM2 pins, the output voltage set point
increases. The maximum output deviation is +20%. The value of external resistor can be obtained by trim table shown in next
page.

Application Note
150W Single Output
Output Over Current Protection
TEP 150WI series employ a fixed current limit to prevent damage to components within the converters, and will also protect the
load provided that the current limiting crossover point is set at a current value that the load can handle without damage.
Normally, the current limit is maintained at approximately 105~120 percent of rated current for TEP 150WI series. If the output
load current is over rating, the output current will keep in a constant value. And the output voltage will fall.
All of the TEP 150WI series current limiting supplies are self restoring; that is, when the overload is removed or corrected, the
output voltage is automatically restored to the previously set value.
Otherwise, if the output resistance is become short, it will operate in hiccup protection. The details are shown below.

Notes:
CV Region: In normal operation. The output current in spec.
Condition: Resistance Load > Vout / Iout (CC Point)
CC Region: If the output load current is over rating, the output current will keep in a constant value. And the output voltage
will fall.
Condition: Resistance Load < Vout / Iout (CC Point)
Hiccup Protection: If the output resistance is become short. It will operate in hiccup protection.
Condition: Vout < 4.3V (typ.) to Output Short. (TEP 150-xx12WI, TEP 150-xx13WI)
Vout < 8.0V (typ.) to Output Short. (TEP 150-xx15WI, TEP 150-xx16WI)
Vout < 13V (typ.) to Output Short. (TEP 150-xx18WI)
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 it 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 “Shunt
Down” 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 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 extremely high
reliability.

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. 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 12V is 0.5 mA.

Safety and Installation Instruction
The TEP 150 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 30A for TEP 150–24xxWI and 15A for TEP 150–48xxWI. Based on the information provided in this
datasheet 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 150 series of DC/DC converters has been calculated using
Bellcore TR-NWT-000332 Case 1: 50% stress, Operating Temperature at 40°C. The resulting figure for MTBF is 1’525’000
hours.
MIL-HDBK 217F Notice2 Full Load, Operating Temperature at 40°C, Air Flow = 400LFM (Ground, Benign, controlled
environment ) The resulting figure for MTBF is 135’300 hours.
