XP Power Releases 12 & 20W DC-DC Converters With 4:1 Input Range

January 20, 2009 by Jeff Shepard

XP Power announced two additions to their low power dc-dc converter product line-up. Encapsulated in a DIP24 metal package, the 12W JTF12 series measures 1.25 x 0.8 x 0.4" (31.75 x 20.32 x 10.4mm). The 20W JTM20 series uses the 1 x 2" (25.40 x 50.80mm) industry standard mounting format.

These new converters are said to offer a high efficiency of up to 91% by using the latest design techniques and components and are suitable for a large variety of applications and products. Additionally, by using popular mechanical formats, these isolated and regulated converters are also said to be well suited as low cost drop-replacements for existing designs; saving the need to re-design the PCB layout.

Offering a wide 4:1 input range, both series have 9-36 or 18-75Vdc inputs that cover the nominal input voltages of 12, 24 or 48Vdc. Comprising of single and dual output variants, there are a total of 28 models across the two series. Single output models offer 3.3, 5, 12 or 15Vdc while dual output voltages are +/- 5, +/- 12 or +/- 15Vdc. Output voltages are fully regulated to within +/- 0.5% over all input ranges and to less than +/- 1.0% across all load conditions. Both devices feature an input to output and input/output to case isolation of 1,600Vdc for up to 1 minute.

With a maximum case temperature of +105°C, the units can operate at full output power from -40 to +60°C without derating. No additional heat sinking or forced airflow is required making the converters suitable for most operating environments.

The converters comply with MIL-STD-217F for predicted lifetime. The JTF12 has a MTBF in excess of 1 million hours and the JTM20 is rated at 560 thousand hours. A remote on/off signal is included as standard, allowing engineers to design-in the ability to sequence converter start-up or control the outputs.

The JTM12 single output units are priced at $32 for a 500 pieces order. The JTM2012 dual output model is priced at $44 for a 500 pieces order.
