R1800K010A-TR

Overview

The R1800K010A-TR is a buck DC/DC converter from the Nisshinbo R1800K series, designed for energy harvesting applications. It operates with an input voltage range of 2 V to 5.5 V and provides a fixed output voltage of 3.3 V. The device delivers a maximum output current of 1 mA while maintaining an ultra-low quiescent current of 144 nA. It utilizes a DFN-2730-12 package and supports SMD/SMT mounting.

Feature Summary

• Ultra-low power consumption architecture optimized for energy harvesting systems
• Integrated step-down topology for efficient voltage regulation
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Energy harvesting circuits
• Low-power sensor nodes
• Battery-powered IoT devices

Procurement Notes

Verify the specific suffix against official datasheets to confirm output voltage and package type. Ensure compatibility with required input ranges and thermal constraints. Confirm RoHS compliance status through manufacturer documentation before integration into final assemblies.

Selection Notes

Select this component when ultra-low standby current is critical for extending battery life in intermittent duty cycles. The fixed 3.3 V output suits logic levels requiring stable supply without external feedback networks. Evaluate thermal performance within the DFN-2730-12 footprint for high-density layouts.

Part Context

Part of the R1800K family focusing on low-quiescent-current switching regulators. This series targets applications where minimal self-consumption is essential, such as ambient energy collection systems. The R1800K010A-TR variant specifically provides a regulated 3.3 V output.

Replacement Considerations

Check Nisshinbo R1800K014A-TR or R1800K019A-TR for alternative fixed output voltages within the same series. Verify pinout and thermal characteristics match existing board layout requirements before substitution.
