R1211D002A-TR-FE

Overview

The R1211D002A-TR-FE is a PWM step-up DC/DC controller designed for positive output voltage regulation. It operates within an input voltage range of 2.5 V to 6 V and delivers a switching frequency of 700 kHz. The device supports a single output configuration and functions reliably across an extended temperature range from -40°C to +85°C. It is housed in a compact 6-pin SON package measuring 2.6x1.6 mm, suitable for space-constrained surface-mount applications.

Feature Summary

• PWM-based step-up topology for efficient voltage boosting
• Wide input voltage compatibility for flexible power sources
• High-frequency operation enabling smaller external components

Applications

• Portable electronic devices requiring voltage elevation
• Battery-powered systems with low input voltages
• Embedded modules needing stable boosted supply rails

Procurement Notes

Verify the specific suffix 'TR-FE' corresponds to the reel packaging format and RoHS compliance status as defined by Nisshinbo Micro Devices. Confirm that the 6-pin SON footprint matches your PCB layout requirements. Ensure the operating temperature range aligns with your environmental specifications before finalizing procurement.

Selection Notes

Select this component when a boost converter controller is required for inputs between 2.5 V and 6 V. The 700 kHz frequency allows for reduced passive component size compared to lower-frequency alternatives. Consider the SON-6 package dimensions for spatial constraints. Validate that the external inductor and capacitor selections support the 700 kHz switching rate for optimal efficiency.
