i1C Series 200 W DC/DC Converters

TDK-Lambda i1C series 200 W DC/DC converters are packaged in the 1” x 1” industry standard footprint. These non-isolated, buck-boost DC/DC (step-up, step-down) converters operate from input voltages of either 9 V to 36 V or 18 V to 75 V. The i1C series offers output voltages adjustable from 9.6 V to 28 V with output currents of up to 10 A.

The series is ideal for generating a wide range of high-power DC outputs from 12 V, 24 V, and 48 V system voltages in medical, industrial, test, measurement, and battery-powered equipment such as automated guided vehicles (AGV), industrial mobile robots (IMR), and drones. The i1C models can also replace existing isolated converters, providing a higher power migration path for applications requiring additional output power, as the AC/DC source often provides the isolation barrier.

The i1C has a remarkable efficiency of up to 98%, allowing the converters to deliver high usable power in demanding thermal environments with case temperatures of -40°C to +120°C while providing a longer battery life. Dimensions and pin-out are compatible with the industry standard 1” x 1” footprint, measuring 26.42 mm x 26.42 mm x 10.2 mm (W x L x H). The converters are encapsulated to provide enhanced shock and vibration performance, and the five-sided aluminum case reduces radiated EMI for easier system compliance.

Models include an output voltage adjustment pin, positive or negative logic remote on-off, input undervoltage, overcurrent, and thermal protection.

All models carry the CE and UKCA marks for the Low Voltage and RoHS directives and are designed to the IEC/UL/CSA/EN 62368-1 safety standards. Evaluation boards are available for quick and easy testing.
