XP Power has made two additions to its low-power DC-DC converter product lineup. Encapsulated in a DIP24 metal package, the 12 W JTF12 series measures 31,75 x 20,32 x 10,4 mm while the 20 W JTM20 series uses the 25,40 x 50,80 mm industry standard mounting format.
These new converters 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 ideally suited as low-cost drop-in replacements for existing designs, saving the need to redesign the PCB layout.
Offering a wide 4:1 input range, both series have 9–36 V d.c. or 18–75 V d.c. inputs that cover the nominal input voltages of 12, 24 and 48 V d.c. Comprising 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 15 V d.c. while dual output voltages are ±5, ±12 or ±15 V d.c. 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 1600 V d.c. for up to 1 minute.
With a maximum case temperature of +105°C, the units can operate at full output power from -40°C to +60°C without derating. No additional heatsinking or forced airflow is required, making the converters suitable for most operating environments. 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.
