R1211N002C-TR-FE

Overview

The R1211N002C-TR-FE is a PWM step-up DC/DC controller manufactured by Nisshinbo Micro Devices Inc. It operates with a switching frequency of 700kHz and supports an input voltage range of 2.5V to 6V. The device provides a single output capable of delivering up to 50mA at 15V. It functions within a temperature range of -40°C to +85°C and utilizes a SOT-23W-6 package.

Feature Summary

• Voltage mode control for boost topology
• Integrated enable control feature
• Maximum duty cycle of 90%

Applications

• Portable electronic devices requiring step-up power conversion
• Battery-powered systems operating within the specified voltage range
• General purpose DC/DC conversion in compact form factors

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm that the SOT-23W-6 package dimensions align with your PCB footprint requirements. Ensure the component meets RoHS compliance standards if mandated by your project specifications. Cross-reference the manufacturer part number with distributor listings to confirm current availability status.

Selection Notes

Select this controller when a synchronous rectifier is not required and a non-synchronous boost solution is acceptable. Consider the 700kHz switching frequency for balancing efficiency and component size. Verify that the 50mA output current capability meets the load requirements. Ensure the input voltage range covers the minimum battery discharge voltage of the application.
