JCM Series DC-DC Power Converters

XP Power's JCM series of low-power, metal-cased DC-DC converters are aimed at space constrained portable applications. These highly efficient board mounted converters provide either single or dual regulated outputs from an ultra-compact 1 x 1 x 0.39 inch package. Achieving an efficiency of up to 89%, these tiny units are ideal for applications where PCB space for the converter needs to be kept to the minimum and an industry standard package pin-out is required. These products can replace existing 1" x 2" packages thus reducing required board space by 50%.

With a 2:1 wide input range, the JCM20 series offers three input ranges of 9-18, 18-36, or 36-75 V_DC inputs. Single output models provide +3.3, +5, +12, or +15 V_DC, while the duals offer ±5, ±12, or ±15 V_DC. 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 V_DC is provided across the range.

Able to work in most environments, the JCM can operate at full load from -40°C to +65°C without the need for any additional heatsinking or forced airflow. With derating the JCM can operate up to +100°C.

The series features 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.
