Application Note TRA 1 Series TRA 1 Series 1W, SIP, Single & Dual Output DC/DC Converters Features ►Standard SIP-7 Package ►Semi-regulated Output Voltage ►High Efficiency to 88.5% ►I/O-isolation 1000VDC ►Operating Temp. Range –40°C to +85°C ►UL/IEC/EN 60950-1 Safety (Approval pending) ►Industry Standard Pinout ►3 Years Product Warranty Applications ►Distributed power architectures ►Workstations ►Computer equipment ►Communications equipment General Description The TRACO TRA 1 series is a new range of isolated 1W DC/DC converter modules in a small SIP-package. There are 24 models available with 5V, 12V or 24VDC input and single-or dual-output voltages. These products provide have a typical load regulation of 2.5% to 5.0% depending on model. The TRA1 DC/DC converters are a compromise between a more expensive fully regulated converter and a non-regulated converter. They offer the designer a new solution for many cost critical applications where the output voltage variation has to be kept in a certain limit under all load conditions.

Highly inductive source impedances can affect the stability of the power module. In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure startup. Capacitor mounted close to the power module helps ensure stability of the unit, it is commended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 KHz) capacitor of a 2.2µF for the 5V input devices, a 1.0µF for the 12V input devices and a 0.47µF for the 24V devices. http://www.tracopower.com Page 31 of 35 Application Note TRA 1 Series Mechanical Dimensions 19.5 [0.77] 0.5 [0.02] 2.35 [0.09] 10.2 [0.40] Pin 1 2 4 5 6 3.2 [0.13] 0.5 [0.02] Pin Connections Single Output +Vin -Vin -Vout No Pin +Vout Dual Output +Vin -Vin -Vout Common +Vout 2X2.54 2.54 5.08 [0.10] [0.20] [2X0.10] 18.5 [0.73] T=6.1[0.24] for 5V & 12V Input Models T=7.1[0.28] for 24V Input Models 4 5 6 0.25 [0.01] 2 0.50 [0.02] 1.

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 in 5Vin, 12Vin, 24Vin with maximum rating of 500mA, 200mA, 100mA.. 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.
