TDK expands i1C series with new 200W non-isolated buck-boost DC-DC converters

These versatile converters are ideal for applications requiring a broad range of high-power DC outputs, such as in 12V, 24V, and 48V systems. Key markets include medical devices, industrial automation, test and measurement equipment, and battery-powered systems like Automated Guided Vehicles (AGVs), Industrial Mobile Robots (IMRs), and drones. By replacing isolated converters with the i1C models, users can access a higher power output without sacrificing efficiency or reliability.

High efficiency for demanding environments

With an efficiency rating of up to 98%, the i1C series operates effectively in challenging thermal conditions, maintaining case temperatures between -40°C and +120°C. The compact design, with dimensions of 26.42 x 26.42 x 10.2mm, makes it an excellent fit for space-constrained applications. Encapsulated in a robust five-sided aluminium case, these converters are engineered to withstand high levels of shock and vibration while minimizing radiated EMI, simplifying system compliance.

The series also includes critical features like output voltage adjustment, positive or negative logic remote on/off control, and comprehensive protection against under-voltage, over-current, and thermal overloads.

Certified for global use

The i1C models carry CE and UKCA marks, certifying compliance with the Low Voltage and RoHS Directives. They are also designed to meet the stringent IEC/UL/CSA/EN 62368-1 safety standards, ensuring safe operation across a range of environments. Evaluation boards are available to facilitate easy testing and integration into designs.

Applications the i1C series is designed for use in:

• Medical equipment
• Automated Guided Vehicles (AGVs)
• Industrial Mobile Robots (IMRs)
• Drones
• Test and measurement equipment
• Industrial systems
• Battery-powered devices
