New High Density 50W Device Adds to Current Range of DC / DC Converters



24th July, 2002, Tucson, Arizona - C&D Technologies has expanded its family of high-density quarter brick DC-DC converters with a highly integrated 50W, dual output device that will allow designers to reduce application component count and minimize noise.

Ideal for distributed power architectures and telecommunications
requirements, the new VSX50MD23 is an isolated DC-DC converter
that employs the C&D Technologies proprietary V series high-density technology to achieve an 89% efficiency rating. This minimizes the need for heat sinking while a low output ripple reduces the need for additional filtering. Component count can be further reduced as a result of integrated features that include remote on/off with positive or negative logic options, output voltage trim, output current limit, input filtering and built in non-latching protection against undervoltage, overvoltage and short circuits.

The VSX50MD23 has a wide 36-75V input range for design flexibility and offers 3.3 and 5.0V outputs with maximum output noise voltages of 60 and 80mV respectively. Isolation between input and outputs is rated at 1500VDC and power can be traded between the dual outputs as required. Output voltage tracking takes place at turn-on and turn-off under all line and load conditions.

The new converter is approved to UL/cUL 1950 and EN60950 and can operate with a baseplate temperature of between -40 and 100°C.

Available now, pricing for the VSX50MD23 is $95 in OEM quantities.
