Ultra compact 20-W DC-DC converters achieve 51-W per cubic inch power density
Achieving what XP claims is an industry leading power density of up to 51 Watts per cubic inch and an efficiency of up to 89%, the units are ideal for applications where PCB space for the converter needs to be kept to the minimum and an industry standard package pinout is required. The products can replace existing 1 x 2 inch packages thus reducing required board space by 50%.
The JTK20 series accommodates an ultra wide 4:1 range, and is available with either 9 – 36 or 18 – 75 VDC input voltage. With a 2:1 wide input range, the JCM20 series offers three input ranges of 9 – 18, 18 – 36 or 36 – 75 VDC inputs. Single output models provide +3.3, +5, +12 or +15 VDC, while the duals offer ±5, ±12 or ±15 VDC. All outputs are fully regulated to within ±0.5% over all input and load conditions for the single output models and less than ±1.0% for the dual outputs. Single output models have an output trim that allows adjustment within ±10% of nominal output. Input to output and input/output to case isolation of 1,600 VDC is provided across the range.
Able to work in most environments, the JTK20 can operate at full load from -40 to +55 °C, and the JCM20 up to +65 °C, without the need for any additional heatsinking or forced airflow. With derating the JCM20 can operate up to +100 °C, and +105 °C for the JTK20.
Both series feature remote on/off control. This can be used to control the output rails or to sequence start-up procedures. All units also feature overvoltage, overload and short circuit protection.
All products have a three year warranty.
The JCM20 and JTK20 are available from Farnell or direct from XP Power.
