XP Power’s JTF Series of low-power DC-DC converter product line-up is encapsulated in a 24-DIP metal package. The JTF series measures only 1.25 x 0.8 x 0.4 inches. These 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 re-design the PCB layout.
Offering a wide 4:1 input range, the JTF series has a 9-36 VDC or 18-75 VDC input that cover the nominal input voltages of 12, 24 or 48 VDC. Single-output models offer 3.3, 5, 12 or 15 VDC while dual-output voltages are +/-5, +/-12 or +/-15 VDC. 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 1,600 VDC 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 heat sinking or forced airflow is required making the converters suitable for most operating environments.
These highly reliable DC-DC converters comply with MIL-STD-217F for predicted lifetime and have a MTBF in excess of 1 million 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.
