R1280D002A-TR-FE

Overview

The R1280D002A-TR-FE is a CMOS-based dual-channel PWM step-up and inverting DC/DC controller manufactured by Nisshinbo Micro Devices. It operates within an input voltage range of 2.5 V to 5.5 V with a typical operating supply current of 1.4 mA. The device supports a switching frequency of 700 kHz and delivers an output current of 20 mA per channel. It features two independent outputs and utilizes a 10-VFDFN surface-mount package. The component functions reliably across an extended temperature range from -40°C to +85°C, designed for efficient power management in compact electronic systems.

Feature Summary

• Dual-channel architecture supporting simultaneous step-up and inverting topologies
• Integrated PWM control mechanism for precise voltage regulation
• CMOS technology enabling low standby current consumption

Applications

• Portable battery-powered devices requiring multiple voltage rails
• White LED backlighting circuits with inverting bias requirements
• Embedded systems needing compact dual-output power solutions

Procurement Notes

Verify the specific ordering suffix and manufacturer documentation to confirm functional equivalence, as the R1280D002A-TR-FE may be discontinued or superseded by updated revisions. Cross-reference the official datasheet for pinout compatibility and thermal characteristics before integration. Ensure that the supplier provides valid traceability records and confirms RoHS compliance status according to current regulatory standards.

Selection Notes

Select this component when a dual-output solution combining boost and inverting capabilities is required within a small footprint. The 700 kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 2.5 V minimum input voltage constraint against the system's available power source to ensure reliable startup and operation under all load conditions.

Part Context

This part belongs to the R1280D series of switching voltage regulators from Nisshinbo Micro Devices. The series focuses on providing flexible power conversion options in minimal packages. The R1280D002A variant specifically addresses applications needing both positive boosted and negative inverted voltages from a single low-voltage input source, serving as a specialized PMIC solution.

Replacement Considerations

Public sources indicate the R1280D002B-TR-FE as a related variant within the same product family. Verify electrical parameter alignment and pin compatibility before substitution.
