JTD Series 4:1 Input DC-DC Converters

XP Power JTD15 and JTD20 series of board-mounted DC-DC converters target cost sensitive applications where a compact unit with a wide input range is required. The range is aimed at offering a power solution in multiple markets, such as instrumentation, broadcast, networking, telecommunications, and data communications.

Offering 15 W and 20 W, the JTD15 and JTD20 DC-DC modules employ the latest design technologies to provide high efficiency in an industry-standard format, an ultra-wide 4:1 input voltage range, and an extended operating temperature range of -40°C to +100°C.

Providing regulated single and dual output models in the range, the JTD15 and JTD20 series offer a choice of wide 4:1 input voltage ranges of 9 V_DC to 36 V_DC or 18 V_DC to 75 V_DC, making them suitable for 12 V_DC, 24 V_DC, and 48 V_DC input applications in industrial or telecom/datacom applications. Output voltages include 3.3 V_DC, 5 V_DC, 12 V_DC, and 15 V_DC single outputs or ±5 V_DC, ±12 V_DC, and ±15 V_DC dual outputs. Input to output isolation is 1600 V_DC.

Coming in small-size metal-cased packages with dimensions of only 40.64 mm x 25.4 mm x 10.4 mm (1.6" x 1.0" x 0.41"), the modules provide designers with more board real estate to add other features, or to reduce the size of the overall end product. Offering efficiency from 82% to 90%, with an average efficiency of 85%, the modules also run cooler and dissipate less heat in end systems, making them capable of operating in most environments with no need for airflow or heatsinks. The modules deliver full output power up to +70°C with no derating.

Other features include ±10% output voltage trim with an external resistor for single output models and remote ON/OFF as standard on all models. Both JTD15 and JTD20 ranges also meet EN55032 Level A EMI standards with no external filtering required, thereby saving valuable PCB space.
