Overview
The R1211N002B-TR-FE is a boost DC/DC controller manufactured by Nisshinbo Micro Devices. It operates within an input voltage range of 2.5 V to 6 V and delivers an adjustable output voltage. The device functions as a PWM step-up converter with a switching frequency of 300 kHz and a maximum duty cycle of 94%. It features a low operating supply current of 600 uA, making it suitable for power-efficient applications requiring single-output step-up conversion.
Feature Summary
- Boost topology for step-up DC/DC conversion
- Adjustable output voltage capability
- Low operating supply current consumption
Applications
- Portable electronic devices requiring battery voltage boosting
- Consumer electronics with limited power supply constraints
- General-purpose step-up power management circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status prior to integration. Check for obsolescence notices as availability may be restricted. Ensure the specific suffix matches design requirements for package and tape specifications.
Selection Notes
Select this controller when a boost topology is required for input voltages between 2.5 V and 6 V. Consider the 300 kHz switching frequency for inductor size trade-offs. Evaluate the 600 uA quiescent current against system standby power budgets. Verify that the adjustable output range meets the target load requirements.
Part Context
This component belongs to the R1211 series of switching controllers from Nisshinbo Micro Devices. The series focuses on efficient power management solutions. The TR-FE suffix indicates the reel packaging format and environmental compliance. It is part of the broader portfolio of PMICs designed for mobile and portable applications.
Replacement Considerations
Cross-reference with other boost controllers from Nisshinbo such as the R1211D002D-TR-FE. Verify pin compatibility and electrical parameter alignment before substitution. Consult official datasheets for functional equivalence.
