IR3892MTRPBF

IR3892MTRPBF Description

The IR3892MTRPBF from Infineon Technologies is a high-efficiency, dual-output synchronous buck regulator from the SupIRBuck® series. Designed for demanding power management applications, it delivers up to 6A per channel with an adjustable output voltage range of 0.5V to 18.06V. This obsolete but robust IC operates over a wide input voltage range (1V to 21V) and supports switching frequencies from 300kHz to 1MHz, enabling flexible design optimization for efficiency and component size. Packaged in a surface-mount PQFN and compliant with ROHS3 and REACH standards, it is ideal for space-constrained designs requiring high power density.

IR3892MTRPBF Features

• Dual-Output Buck Regulator: Provides two independent adjustable outputs, reducing board space and BOM complexity.
• High Efficiency: Synchronous rectification and SupIRBuck® architecture minimize power losses, enhancing thermal performance.
• Wide Input Range (1V–21V): Supports diverse power sources, including batteries and intermediate bus voltages.
• Programmable Frequency (300kHz–1MHz): Balances efficiency and EMI performance for optimized designs.
• Compact PQFN Package: Suitable for high-density PCB layouts in industrial and embedded systems.
• Robust Protection: Integrated features (e.g., thermal shutdown, UVLO) ensure reliability in harsh environments.

IR3892MTRPBF Applications

• Telecom/Networking Equipment: Point-of-load (POL) regulation for FPGAs, ASICs, and processors.
• Industrial Automation: Power supplies for motor drives, PLCs, and control systems.
• Embedded Computing: Voltage regulation in single-board computers and IoT devices.
• Consumer Electronics: Efficient power delivery for displays, storage devices, and portable gadgets.

Conclusion of IR3892MTRPBF

The IR3892MTRPBF excels in multi-rail power systems, offering high current output, flexibility, and compact integration. While marked obsolete, its SupIRBuck® technology and dual-output capability make it a strong choice for legacy designs or inventory-based projects requiring reliable, high-performance voltage regulation. Engineers should verify replacement options or consider alternative Infineon regulators for new designs.
