R1211D102C-TR-FE

Overview

The R1211D102C-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 supports a switching frequency of 300 kHz. The device is housed in a compact 6-SON package with dimensions of 2.6 x 1.6 mm. It functions as a single-output regulator suitable for applications requiring efficient voltage boosting. The operational temperature range spans from -40°C to +85°C, ensuring reliability across standard industrial environments.

Feature Summary

• PWM-based step-up DC-DC control architecture
• Positive output voltage regulation capability
• Compact 6-SON surface-mount packaging

Applications

• Battery-powered portable electronics
• Low-voltage system power boosting
• General-purpose positive voltage regulation

Procurement Notes

Verify the specific suffix 'TR-FE' against official Nisshinbo documentation to confirm tape-and-reel packaging and lead-free status. Ensure the target application voltage aligns with the 2.5 V to 6 V input specification. Cross-reference the 300 kHz switching frequency requirements with external component selections. Confirm availability status as some sources indicate potential obsolescence or substitute recommendations.

Selection Notes

Select this controller when a fixed 300 kHz switching frequency is acceptable for the design. The 2.5 V minimum input voltage dictates suitability for single-cell lithium battery applications or systems with higher initial supply rails. The 6-SON package requires appropriate PCB footprint planning. Verify that the external inductor and diode ratings support the required boost ratio and current levels for the intended load.

Part Context

This component belongs to the R1211 series of DC-DC controllers manufactured by Nisshinbo Micro Devices Inc. The series focuses on efficient power management solutions using PWM technology. The manufacturer provides various package options and voltage configurations within this family to address diverse power conversion needs in consumer and industrial electronics.

Replacement Considerations

Official documentation indicates this product may be obsolete. Review Nisshinbo's recommended substitute part numbers for direct replacements. Ensure any alternative maintains compatibility with the 6-SON footprint and 300 kHz operating frequency if pin-out and thermal performance are critical constraints.
