XP Power has added to the company's
range of low power metal cased DC-DC converters with the launch of the
20 Watt JCM20 and JTK20 series. Aimed at space constrained portable
applications, these highly efficient board mounted converters provide
either single or dual regulated outputs from an ultra compact 25.4 x
25.4 x 9.90 mm (1 x 1 x 0.39 inch) package.
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.
