Infineon IR3829MTRPBF: High-Performance Synchronous Buck Regulator for Advanced Power Management Solutions
In the realm of modern electronics, efficient and reliable power conversion is paramount. The Infineon IR3829MTRPBF stands out as a high-performance, fully integrated synchronous buck regulator designed to meet the rigorous demands of advanced power management solutions. This compact yet powerful IC is engineered to deliver exceptional efficiency, precision, and thermal performance in a wide array of applications, from networking and telecommunications equipment to industrial systems and computing servers.
At the core of the IR3829MTRPBF is a highly efficient synchronous buck topology that minimizes power loss and maximizes battery life in portable devices. With an input voltage range spanning from 4.5V to 21V, it offers exceptional flexibility for both standard and challenging power environments. The device can deliver a continuous output current of up to 3A with peak efficiency exceeding 95%, ensuring optimal thermal management and reducing the need for external heat sinks. This high efficiency is achieved through the integration of low-resistance MOSFETs and a advanced control algorithm that minimizes switching and conduction losses.

Precision regulation is another hallmark of this regulator. It features a reference voltage accuracy of ±1% over the entire temperature range, ensuring stable and reliable power delivery to sensitive loads such as FPGAs, ASICs, and processors. The switching frequency is programmable from 200kHz to 1.5MHz, allowing designers to optimize the solution for size or efficiency, and even synchronize to an external clock to avoid beat frequencies in noise-sensitive applications.
The IR3829MTRPBF is designed with robustness in mind. It incorporates a comprehensive suite of protection features, including over-current protection (OCP), over-voltage protection (OVP), under-voltage lockout (UVLO), and thermal shutdown. These safeguards ensure the longevity and reliability of both the regulator itself and the end system. Furthermore, its proprietary Advanced Control IC technology from Infineon provides excellent line and load transient response, maintaining output stability under dynamic operating conditions.
Housed in a compact 3mm x 3mm PQFN package, the device enables high power density designs, making it ideal for space-constrained applications. The integration of the controller, high-side and low-side MOSFETs, and bootstrap diode into a single package simplifies the design process, reduces the bill of materials (BOM), and accelerates time-to-market.
ICGOOODFIND: The Infineon IR3829MTRPBF is a superior integrated solution that combines high efficiency, precise regulation, and robust protection in a minimal footprint. It is an exemplary choice for engineers developing next-generation power systems that demand performance, reliability, and compactness.
