Voltage Regulators - DC DC Switching Regulators datasheet and documents for IR3825MTRPBF

IR3825MTRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The IR3825MTRPBF is a highly integrated single-input synchronous buck regulator from Infineon Technologies, designed for high-current applications. It delivers up to 20A output current with an adjustable voltage range of 0.6V to 1.8V. The device operates with an input voltage between 4.5V and 21V and supports switching frequencies from 300kHz to 1.2MHz. Packaged in a compact 17-PowerVQFN (4x5mm) surface-mount case, it integrates power FETs and control logic. The component functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates synchronous power MOSFETs and controller logic into a single compact package to minimize external component count.
Features adaptive on-time control architecture for fast transient response and stable operation across varying load conditions.
Includes comprehensive protection mechanisms such as overcurrent protection, thermal shutdown, and undervoltage lockout.

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for central processing units (CPUs)
Graphics processing unit (GPU) power delivery systems
Network equipment and telecommunications infrastructure power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific revision level against the latest official datasheet before integration, as manufacturing updates may occur. Confirm that the 17-PowerVQFN footprint matches the target PCB layout exactly. Ensure thermal design accounts for the maximum junction temperature rating under full load conditions. Check for any recent product discontinuation notices or lifecycle status changes directly from the manufacturer.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-phase solution capable of delivering 20A is required without multiphase interleaving complexity. It is suitable for designs prioritizing board space efficiency due to its high integration level. Consider the input voltage range compatibility with the system's main rail. Evaluate thermal performance requirements to ensure adequate heat dissipation through the exposed pad.
