General Description
TEN 20WIR DC/DC converters provide up to 20 watts of output power in an industry standard package and footprint. These
units are specifically designed to meet the power needs of low profile. All models feature with 4:1 ultra wide input voltage
of 9~36 VDC, 18~75 VDC and 43~160 VDC, ultra low quiescent current, and built-in EMI filters. Comprehensively protected
against over-current, over-voltage and input under-voltage protection conditions, and trimmable output voltage.

Application Note
TEN 20WIR Series
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 inductor is recommended to minimize input reflected ripple current. The inductor is simulated
source impedance of 2.2μH. The inductor 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 about 150 percent of rated current for TEN 20WIR single output 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.
One of the problems resulting from over current is that excessive heat may be generated in power devices, 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.
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 Voltage Adjustment
Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a module. This is
accomplished by connecting an external resistor between the TRIM pin and either the +OUTPUT or -OUTPUT pins. With an external
resistor between the TRIM and -OUTPUT pin, the output voltage set point increases. With an external resistor between the TRIM
and +OUTPUT pin, the output voltage set point decreases.

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
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 4A for TEN 20-24xxWIR modules and 2A for TEN 20-48xxWIR modules and 1A for TEN 20-72xxWIR 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 20WIR SERIES of DC/DC converters has been calculated using
Bellcore TR-NWT-000332 Case I: 50% stress, Operating Temperature at 40C° (Ground fixed and controlled environment ). The
resulting figure for MTBF is 1.630×106 hours. MIL-HDBK 217F NOTICE2 FULL LOAD, Operating Temperature at 25°C. The resulting
figure for MTBF is 4.950×105 hours.
