R1810L027A-E2

Overview

The R1810L027A-E2 is a non-isolated boost DC/DC converter from the R1810x series by Nisshinbo Micro Devices. It operates with an input voltage range of 350 mV to 2.1 V and provides a fixed output of 2.6 V. The device features ultra-low quiescent current of 600 nA, making it suitable for energy harvesting applications. It is housed in a compact 14-UFDFN exposed pad package (3.5x2.7 mm) and supports surface mount installation. The operational temperature range spans from -40°C to +85°C.

Feature Summary

• Ultra-low quiescent current consumption for extended battery life
• Designed for energy harvesting and low-voltage input scenarios
• Compact footprint suitable for space-constrained designs

Applications

• Energy harvesting systems
• Space-constrained portable electronics
• Low-voltage power regulation

Procurement Notes

Verify the specific suffix E2 against official datasheets to confirm package and tape/reel specifications. Ensure compatibility with the required input voltage range of 350 mV to 2.1 V. Confirm that the fixed 2.6 V output meets system requirements. Check RoHS compliance status via manufacturer documentation before integration.

Selection Notes

Select this component when input voltages are extremely low, such as those from energy harvesters or depleted batteries. The 600 nA IQ is critical for minimizing standby losses. The 14-DFN package offers a small solution size compared to larger converters. Ensure the load current requirements do not exceed the internal switch limits defined in the electrical characteristics table.

Part Context

This part belongs to the R1810x series of high-efficiency, low-noise boost converters. It is positioned as a specialized regulator for applications requiring minimal self-consumption. The series targets markets where power efficiency at very low input levels is paramount, distinguishing it from standard general-purpose boost regulators.

Replacement Considerations

Check for direct pin-compatible alternatives within the R1810x family with different output voltages if system voltage needs change. Verify thermal performance similarities in the DFN-14 package when substituting with other manufacturers' ultra-low IQ boost converters.
