(10,9 mm) Parallelable, with N+M fault tolerance Low noise ZCS/ZVS architecture Shown actual size: 4.6 x 2.2 x 0.5 in 117 x 56 x 12,7 mm Typical Applications: distributed power; off-line systems using power PFC front-ends; electric vehicles 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.
