R1211N002A-TR-FE

Overview

The R1211N002A-TR-FE is a PWM step-up DC-DC controller IC manufactured by Nisshinbo Micro Devices. It functions as a boost regulator that converts a lower input voltage to a higher output voltage. The device operates with an operating supply voltage range of 2.5 V to 6 V and features an operating supply current of 600 uA. It utilizes a switching frequency of 805 kHz and is housed in a 6-pin SOT-23W package.

Feature Summary

Functions as a positive output step-up DC-DC controller for voltage boosting applications
Operates within a wide input voltage range from 2.5 V to 6 V
Designed for low power consumption with an operating supply current of 600 uA

Applications

Portable electronic devices requiring voltage step-up
Battery-powered systems needing efficient DC-DC conversion
Low-power consumer electronics utilizing PWM control

Procurement Notes

Verify the specific suffix TR-FE confirms the tape and reel packaging format required for automated assembly processes. Ensure the component meets RoHS compliance standards if environmental regulations apply to your manufacturing line. Cross-reference the 6-pin SOT-23W footprint dimensions against your PCB design guidelines to guarantee mechanical fitment and thermal performance requirements are satisfied before finalizing procurement orders.

Selection Notes

Select this controller when a compact solution for stepping up voltages between 2.5 V and 6 V is required. The 805 kHz switching frequency offers a balance between efficiency and external component size. Consider the 600 uA quiescent current for battery life optimization in portable applications. The SOT-23W package provides a small form factor suitable for space-constrained designs compared to larger alternatives.

Part Context

This component belongs to the R1211N series of PWM controllers from Nisshinbo Micro Devices. The series focuses on efficient power management solutions for portable electronics. The R1211N002A variant specifically addresses step-up converter needs, distinguishing it from buck or LDO regulators within the broader product portfolio.
