R1211N002D-TR-FE

Overview

The R1211N002D-TR-FE is a single-output boost DC/DC controller manufactured by Nisshinbo Micro Devices. It operates with a switching frequency of 360 kHz and supports an input supply voltage range of 2.5V to 6V. The device features a maximum duty cycle of 90% and does not include synchronous rectification. It is housed in a 6-pin SOT-23W package and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Boost topology for step-up voltage conversion
• Integrated enable control feature
• Compact 6-pin SOT-23W surface-mount packaging

Applications

• Portable electronic devices requiring voltage step-up
• Battery-powered systems needing regulated higher output voltages
• General-purpose DC/DC power management circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'TR-FE' matches the required tape-and-reel packaging and RoHS compliance status. Check current availability as this part may have limited stock or be subject to discontinuation notices. Ensure the ordering information aligns with the exact datasheet specifications for the Nisshinbo Micro Devices Inc. product line.

Selection Notes

Select this controller when a non-synchronous boost solution is required for moderate power applications. The 360 kHz frequency offers a balance between efficiency and component size. Consider the 2.5V minimum input voltage for compatibility with single-cell lithium batteries. The absence of synchronous rectification simplifies the external circuit design but may impact peak efficiency compared to synchronous alternatives.

Part Context

This component belongs to the R1211 series of switching controllers from Nisshinbo Micro Devices. The series focuses on efficient power management solutions for portable electronics. The R1211N variant specifically addresses boost converter requirements, distinguishing it from other topologies in the family. It complements the company's portfolio of analog and power management integrated circuits.

Replacement Considerations
