IRU3046CFTR

Overview

The IRU3046CFTR is a triple-output power management IC from Infineon Technologies, featuring one synchronous step-down (buck) converter and two low-dropout (LDO) regulators. It operates within a switching frequency range of 200kHz to 400kHz. The device is housed in a 24-TSSOP package and is designed for applications requiring multiple regulated voltage rails from a single input source.

Feature Summary

• Integrates three independent output channels combining synchronous buck and linear regulation topologies
• Supports adjustable switching frequencies between 200kHz and 400kHz for optimized efficiency and component size
• Provides compact integration of mixed-signal power regulation in a small outline package

Applications

• Portable electronic devices requiring multiple voltage rails
• Embedded systems with mixed analog and digital power requirements
• Industrial control modules needing stable low-noise supply voltages

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing PCB footprints and thermal management designs. Check for updated replacement components if long-term supply stability is required.

Selection Notes

Select this component when a single IC solution is needed to generate three distinct regulated voltages. Consider the trade-off between the higher efficiency of the synchronous buck channel and the simplicity of the LDO outputs. Evaluate the 24-TSSOP package constraints against available board space and thermal dissipation capabilities.

Part Context

This part belongs to Infineon's portfolio of integrated power management solutions. It consolidates multiple voltage regulation functions into a single device, reducing bill of materials count and assembly complexity compared to discrete regulator implementations.

Replacement Considerations

As the IRU3046CFTR is listed as obsolete, identify equivalent triple-output PMICs from current product lines. Verify pin compatibility and electrical specifications to ensure seamless integration without redesigning the host circuit.
