DC/DC converters achieve 51W power density per cubic inch
1 min read
XP Power has extended its range of low power, metal cased dc/dc converters with the launch of the 20W JCM20 and JTK20 series.
Aimed at space constrained portable applications, these board mounted converters provide either single or dual regulated outputs from a compact 25.4 x 25.4 x 9.90mm package. Said to provide a power density of up to 51W per cubic inch and an efficiency of up to 89%, the units are designed for applications where pcb space for the converter needs to be kept to a minimum.
The JTK20 series accommodates an ultra wide 4:1 range and is available with either 9 to 36 or 18 to 75VDC input voltage. With a 2:1 input range, the JCM20 series offers three input ranges of 9 to 18, 18 to 36 or 36 to 75VDC inputs.
Single output models are designed to provide 3.3, 5, 12 or 15VDC, while the duals offer +/-5, +/-12 or +/-15VDC.
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 1,600VDC is provided across the range.
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.
