15W DC/DC converters

XP Power has unveiled the latest additions to its line of encapsulated PCB mount ultracompact DC/DC converters. Housed in a metal package, the 15W JTK15 and 30W JTL30 series accommodate an ultrawide 4:1 input range. Covering nominal input voltages of 12, 24 or 48Vdc, the units can accept either 9- to 36Vdc or 18- to 75Vdc inputs.

The JTK15 series measures 25.4mm x 25.4mm x 9.9mm and are available in single or dual output models. The JTL30 series measures 50.8mm x 25.4mm x 10.16mm, and offers single, dual or triple output options. Single output models provide 3.3-, 5-, 12- or 15Vdc, with the duals providing 5, 12 or 15Vdc. Triple outputs provide +3.3- or +5Vdc with either 12 or 15Vdc combinations. All outputs are fully regulated and vary no more than 0.5 percent over all input conditions for single output models. Dual and triple outputs vary by less than 1 percent. Additionally, the output voltage can be trimmed by 10 percent on single output models.

The converters feature an input to output and input/output to case isolation of 1,600Vdc for up to 1 minute. Both the JTK15 and JTL30 also feature a remote on/off signal. This can be used to control the output rails or to sequence start-up procedures. All units feature overvoltage and continuous short circuit protection.

The DC/DC converters can operate at full output power from -40C to +50C for the JTK15, and the JTL30 up to +65C, without derating. With a maximum case temperature of + 105C, no additional heat sinking or forced airflow is required making the converters suitable for most operating environments.

The JTK15 and JTL30 series suit applications in a wide variety of mobile, portable and wireless products, and where designers are looking to reduce the size of their end product.

The JTK15 and JTL30 series have a three-year warranty and are available now. Prices range from $38.22 for the JTK15 single output model to $67.08 for JTL30 triple output models in medium quantities.
