Overview
The R1800K020A-TR is a low quiescent current buck DC/DC converter from the Nisshinbo Micro Devices 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 2.3 V. The device delivers an output current of 1 mA while maintaining a typical quiescent current of 144 nA. It utilizes a DFN-2730-12 package and supports surface mount installation.
Feature Summary
- Ultra-low power consumption architecture optimized for energy harvesting systems
- Integrated buck topology for efficient step-down voltage conversion
- Compact DFN-2730-12 surface mount package design
Applications
- Energy harvesting circuits
- Battery-powered sensor nodes
- Low-power portable electronics
Procurement Notes
Verify the specific part number against official Nisshinbo Micro Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required packaging format. Cross-reference datasheet revisions to validate performance parameters before integration into final designs.
Selection Notes
Select this component when ultra-low standby current is critical for extending battery life in intermittent operation scenarios. The fixed 2.3 V output suits logic levels requiring stable regulation from variable input sources like solar or thermal harvesters. Evaluate thermal performance within the small DFN package for high ambient temperature environments.
Part Context
This device belongs to the R1800K series of switching regulators, which are specialized for ultra-low power management. The series focuses on minimizing quiescent current to support applications where energy availability is limited or intermittent, distinguishing it from standard high-current buck converters.
Replacement Considerations
Consult official substitution guides for compatible parts within the R1800K family or equivalent ultra-low IQ buck converters. Verify that alternative components match the 144 nA quiescent current specification and 2730-12 footprint requirements.
