Their exceptionally wide input voltage range means that the new PXC5 DC/DC converters from Lambda can cover more applications with fewer different models, allowing users to save money by reducing stocks. In addition, the converters can be used to ensure the stable operation of equipment in applications – such as battery-powered systems – where the input supply voltage may be subject to large fluctuations.
Lambda’s new single- and dual-output PXC5 converters are rated at 5W and are offered in versions to suit supplies in the ranges 9 to 36V and 18 to 75V. In either case, the converters automatically maintain their output voltage within ± 0.2% of its nominal value over the whole input voltage range.
Designed to be equally suitable for applications in telecommunications, data communications, industrial automation and process control, PXC5 converters incorporate five-sided shielding. When used with a suitably designed printed circuit board, this means that they generate exceptionally low levels of radiated emissions, making them an ideal choice for use in sensitive equipment.
PXC5 DC/DC converters are approved to a wide range of national and international standards, including UL, CSA, EN and CE, making it easier for users to obtain regulatory approval for equipment which incorporates them, even when it is to be sold in multiple markets around the world.
Single output PXC5 DC/DC converters are available with output voltages of 3.3, 5, 12 or 15V, while dual output models are offered with ±5, ±12 and ±15V outputs. Efficiency ranges from 73% to 82% depending on the model, and all types can be used at their full rated power over the temperature range -40º to +70ºC (higher with derating.)
Converters in the PXC5 range use an industry-standard 24-pin DIP package and, measuring just 32 x 20 x 10mm, they are exceptionally economical in their use of valuable board real estate.
