R1800K021A-TR

Overview

The R1800K021A-TR is a buck DC/DC converter from the Nisshinbo Micro Devices R1800K series, designed for energy harvesting applications. It features an input voltage range of 2 V to 5.5 V and provides an adjustable output voltage between 2 V and 4.5 V. The device delivers a maximum output current of 1 mA with an ultra-low quiescent current of 144 nA. Packaged in a DFN-2730-12 surface-mount format, it operates without a shutdown function.

Feature Summary

Ultra-low quiescent current consumption optimized for energy harvesting
Buck topology step-down DC/DC conversion
Wide input voltage compatibility

Applications

Energy harvesting systems
Low-power portable electronics
Battery-powered sensor nodes

Procurement Notes

Verify the specific fixed output voltage setting corresponding to the '021' suffix against the official datasheet before procurement. Confirm that the required load current does not exceed the 1 mA limit. Ensure the design accommodates the DFN-2730-12 package dimensions and thermal requirements for reliable operation.

Selection Notes

Select this component when extremely low standby current is critical for extending battery life or maximizing harvested energy efficiency. It is suitable for applications requiring a single output channel with moderate current demands. Compare against other R1800K variants if different fixed output voltages are needed while maintaining similar power characteristics.

Part Context

This part belongs to the R1800K series of switching regulators manufactured by Nisshinbo Micro Devices. The series focuses on ultra-low power consumption for niche applications like energy harvesting. The 'TR' suffix indicates the reel packaging format used for automated assembly processes.

Replacement Considerations

Other members of the R1800K series may serve as substitutes if they offer the same 144 nA quiescent current and compatible input/output ranges. Verify pinout and package compatibility before swapping.
