TRV 1 Series Application Note DC/DC Converter 5Vdc ±10%, 12Vdc ±10% or 24Vdc ±10% Input 5.0Vdc, 9Vdc, 12Vdc & 15Vdc Single Outputs, 1W, in SIL package Features Single output up to 200mA 1 watts maximum output power High efficiency up to 88% Input to output isolation: 3000Vdc for 1 minute Large operating temperature range from –40°C up to +85°C Approved according to IEC/EN/UL 60950-1 Applications Distributed power architectures Workstations Computer equipment Communications equipment 226037 Complete TRV 1 datasheet can be downloaded at: http://www.tracopower.com/products/trv1.pdf General Description The Tracopower TRV 1 series is a new range of high isolated 1W DC/DC converter modules in a small SIP-package. There are 24 models available with 5V, 12V or 24VDC input and 5Vdc, 9Vdc, 12Vdc or 15Vdc output voltage. These products provided have a typical load regulation of 3.5% to 5.5% depending on model and have a high I/O isolation of 3000Vdc for 1 minute. The TRV 1 DC/DC converters are a compromise between a more expensive fully regulated converter and a non-regulated converter. They offer to designers 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 recommended to use a good high 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.

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 normal-blow fuse with following maximum ratings: TRV 1-05xx 500mA, TRV 1-12xx 200mA and TRV 1-24xx 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.
