45 Features • • • • • • • • • • • 48Vin / 2Vout / 50Watts DC-DC Converter Module Model Number V48C2C50B* DC input range: 36 - 75V Input surge withstand: 50V for 100ms DC output: 2V Programmable output: 10 to 110% Regulation: ±0.2% no load to full load Efficiency: 76% Maximum operating temperature: 100°C at full load Power density: 30W/cubic inch Height above board: 0.43 in. (10,9 mm) Parallelable, with N+M fault tolerance Low noise ZCS/ZVS architecture Typical Applications: telecommunications and distributed power systems Shown actual size: 2.28 x 1.45 x 0.5 in 57,9 x 36,8 x 12,7 mm Product Overview This DC-DC converter module uses 2nd Generation power processing, control and packaging technologies to provide the performance, flexibility and cost effectiveness expected of a mature power component. For example, a plated-cavity core transformer couples widely separated primary and secondary windings, resulting in low in-toout parasitic capacitance and noise. High frequency ZCS/ZVS switching, advanced power semiconductor packaging and thermal management provide high power density with low temperature gradients. Extensive use of silicon integration results in 1/3 the part count of a 1st Generation converter.
