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

The series can generate high-power DC outputs from 12, 24, and 48V system voltages in medical, industrial, test and measurement and battery-powered equipment such as Automated Guided Vehicles (AGVs), Industrial Mobile Robots (IMRs), 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 isolation barrier is often provided by the AC-DC source.

The efficiency of the i1C is up to 98%, allowing the converters to deliver high usable power in demanding thermal environments with case temperatures of -40oC and up to +120oC. The converters low internal losses enable a longer battery life. The dimensions and pin-out are compatible with the industry standard, measuring 26.42 x 26.42 x 10.2mm (W x L x H). 

The i1C is encapsulated, providing enhanced shock and vibration performance to MIL-STD-810G. In addition, the five-sided aluminium case reduces radiated EMI for easier system compliance. As standard, the i1C has an output voltage adjustment pin, positive or negative logic remote on-off, input under-voltage, over-current, and thermal protection.
