i1C 300W DC-DC Non-Isolated Buck-Boost Converters

TDK-Lambda i1C 300W DC-DC Non-Isolated Buck-Boost Converters deliver up to 300W in a compact, industry-standard 1" x 1" footprint, enabling high power density and reduced board area. These modules perform both step-up and step-down voltage conversions from 12V, 24V, or 48V buses. The i1C converters use a non-isolated power topology, offering a low component count and resulting in a low-cost structure and superior performance. The i1C 300W DC-DC converters offer a compact and shielded design with low profile and weight that allows for extremely flexible and robust manufacturing processes. The ultra-high efficiency enables the i1C series to offer a much higher power density in an industry-standard package. Four types of i1C evaluation boards are also being offered.
