R1810Z031A-E2-F

Overview

The R1810Z031A-E2-F is a non-isolated SMD boost DC/DC converter from the Nisshinbo R1810x series. It operates within an input voltage range of 350 mV to 2.1 V and provides a single output. The device features ultra-low quiescent current of 600 nA, making it suitable for energy-efficient applications. It is housed in a WLCSP-15-P1 package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Ultra-low quiescent current consumption of 600 nA for extended battery life
• Non-isolated boost topology designed for point-of-load regulation
• Compact WLCSP-15-P1 surface-mount package for space-constrained designs

Applications

• Industrial equipment power management
• Point-of-load (PoL) conversion stages
• Battery-powered sensor nodes requiring low standby current

Procurement Notes

Verify component authenticity through authorized Nisshinbo Micro Devices channels or certified distributors. Confirm RoHS compliance status via official documentation. Ensure storage conditions align with manufacturer guidelines to maintain solderability and performance integrity prior to assembly.

Selection Notes

Select this model when input voltages are extremely low, starting from 350 mV. The 600 nA IQ is critical for applications prioritizing minimal standby drain. Verify that the WLCSP-15-P1 footprint matches PCB layout constraints and thermal requirements for the specific industrial environment.

Part Context

This part belongs to the R1810x series of non-isolated DC-DC converters. It shares family characteristics such as low quiescent current design but differs in specific electrical parameters and pin configurations compared to other variants like the R1810Z029A-E2-F.

Replacement Considerations

Direct substitutes within the same series include R1810Z029A-E2-F. Verify compatibility regarding input voltage limits and package dimensions before substitution.
