R1800K023A-TR

Overview

The R1800K023A-TR is a fixed-output buck DC/DC converter from Nisshinbo Micro Devices, designed for energy harvesting applications. It features an input voltage range of 2V to 5.5V and provides a fixed 2.7V output. The device is characterized by an extremely low quiescent current of 144nA, optimizing efficiency in low-power systems. It is housed in a DFN2730-EP-12 package.

Feature Summary

• Ultra-low quiescent current consumption of 144nA for high efficiency
• Fixed 2.7V output suitable for energy harvesting circuits
• Wide input voltage range supporting 2V to 5.5V sources

Applications

• Energy harvesting systems
• Low-power battery-operated devices
• Portable electronic equipment requiring minimal standby current

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the fixed 2.7V output voltage matches the target circuit requirements. Ensure the DFN2730-EP-12 footprint aligns with the PCB layout design. Check RoHS compliance status through official manufacturer documentation prior to integration.

Selection Notes

Select this component when ultra-low standby current is critical for system longevity. The fixed 2.7V output limits flexibility compared to adjustable regulators but simplifies design for specific voltage rails. Consider the input voltage range to ensure compatibility with the power source, such as solar or thermal harvesters.
