i1C 200W DC-DC Non-Isolated Buck-Boost Converters

TDK-Lambda i1C 200W DC-DC Non-Isolated Buck-Boost Converters deliver up to 200W in a compact, industry-standard 1" x 1" footprint for high power density and less board area required. These modules operate from a 9V to 36V or 18V to 75V input range and feature a wide adjustable output of 9.6V to 28V to support multiple system load voltages, reducing part number variations. The i1C converters are encapsulated in a five-sided metal case with a -40°C to +120°C temperature range, superior noise characteristics, and electromagnetic interference (EMI) shielding. TDK-Lambda i1C 200W DC-DC converters feature an efficiency of up to 98% to provide a higher power migration path in applications where space is at a premium. This high efficiency also results in a longer battery life and low power consumption. Two types of i1C evaluation boards are also being offered.
