XP Power has unveiled its JCA series of miniature, board-mounted low power DC/DC converters. Measuring just 1 x 0.8 x 0.4inches (25.4mm x 20.3mm x 10mm), the device's shielded metal package is 0.25 inches (6.4mm) shorter than the 1.25inch (31.8mm) industry norm. Using the customary 24-pin DIP layout, the units occupy 20 percent less PCB area than traditional products. This allows designers to reduce the size of new developments or add in more features, while maintaining the industry standard pin-out makes the converter a suitable drop-in replacement for existing designs.

The JCA series comprises 2W, 3W, 4W and 6W models, each offering a choice of four nominal input voltages of 5-, 12-, 24- and 48Vdc. Input options, covering a wide 2:1 voltage range, are 4.5-9Vdc, 9-18Vdc, 18-36Vdc or 36-75Vdc with under-voltage lockout as standard. For each input voltage, single output models offer 3.3, 5, 12 or 15Vdc outputs or the dual output versions provide 5-, 12- or 15Vdc. Outputs are fully regulated, varying no more than 0.3 percent over all input conditions, and less than 1 percent across all load conditions. The JCA series offer basic input to output isolation rated at 1,500Vdc and case to input or output is 500Vdc.

Suitable for a wide variety of application environments, the converters operate from -40C to 100C with derating above 75C. No additional heat sinking or forced air cooling is required. The maximum case temperature is 100C.

The series has EN, UL, CSA and CE safety approvals and meets EN55022-A for conducted emissions and EN55022-B for radiated emissions without any additional components.

The units carry a three-year warranty and are available from stock and also through Newark.

Prices range from $11.21 for OEM quantities of the 2W, JCA02 model to $21.06 for OEM quantities of the 6W, dual output JCA06 model.
