XP Power’s JTL series of encapsulated PCB-mount ultra-compact DC-DC converters are housed in a metal package and accommodate an ultra-wide 4:1 input range. Covering nominal input voltages of 12, 24 or 48 VDC, the units can accept either 9 to 36 VDC or 18 to 75 VDC inputs. The family offers single-, dual- or triple-output options. Single-output models provide 3.3, 5, 12 or 15 VDC, with the duals providing +/-5, +/-12 or +/-15 VDC. Triple outputs provide +3.3 or +5 VDC with either +/-12 or +/-15 VDC 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 convertors feature an input to output and input/output to case isolation of 1,600 VDC for up to 1 minute. They 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.

These highly-efficient DC-DC converters, up to 91%, can operate at full output power from -40°C 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.

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