XP Power has made new additions to its range of encapsulated PCB mount compact DC-DC converters.
Housed in a metal package, the 15 Watt JTK15 and 30 Watt JTL30 series can accommodate a wide 4:1 input range. Covering nominal input voltages of 12, 24 or 48 V d.c., the units can accept either 9 to 36 V d.c. or 18 to 75 V d.c. inputs.
The JTK15 series, measuring just 25,4 x 25,4 x 9,90 mm, is available in single- or dual-output models. The JTL30 series measures 50,8 x 25,4 x 10,16 mm and offers single-, dual- or triple-output options. Single-output models provide 3,3, 5, 12 or 15 V d.c., with the duals providing ±5, ±12 or ±15 V d.c. Triple outputs provide +3,3 or +5 V d.c. with either ±12 or ±15 V d.c. combinations. All outputs are fully regulated and vary no more than ±0,5% over all input conditions for single-output models. Dual and triple outputs vary by less than ±1%. Additionally, the output voltage can be trimmed by ±10% on single-output models.
The converters feature an input-to-output and input/output-to-case isolation of 1600 V d.c. 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 startup procedures. All units feature over-voltage and continuous short circuit protection. With efficiency up to 91% for the JTL30, the converters can operate at full output power from -40°C to +50°C for the JTK15, and the JTL30 up to +65°C, without derating. With a maximum case temperature of +105°C, no additional heat sinking or forced airflow is required, making the converters suitable for most operating environments.
