Infineon PEB2466HV2: A High-Voltage Power Supply Controller for Industrial Applications

The demand for robust, efficient, and intelligent power management is paramount in modern industrial systems. Addressing this need, the Infineon PEB2466HV2 stands out as a highly integrated power supply controller designed specifically for high-voltage industrial applications. This controller combines advanced functionality with resilience, making it a cornerstone for next-generation power conversion units in demanding environments.

Engineered for primary-side control in switch-mode power supplies (SMPS), the PEB2466HV2 is a highly integrated controller IC that significantly reduces the external component count. This integration simplifies design, enhances reliability, and minimizes the overall footprint of the power supply unit. Its architecture is optimized for Quasi-Resonant (QR) operation, a topology renowned for its high efficiency and reduced electromagnetic interference (EMI). By enabling operation at valley switching, the controller minimizes switching losses, which is critical for achieving high efficiency across a wide load range.

A key feature of this controller is its direct connection to high-voltage rails, up to 650 V. This high-voltage startup unit eliminates the need for a separate startup circuit, allowing for a faster and more efficient power-on sequence. Furthermore, it incorporates comprehensive protection features essential for industrial durability. These include over-voltage protection (OVP), over-current protection (OCP), over-load protection (OLP), and over-temperature protection (OTP). Such a suite ensures the system can withstand abnormal operating conditions, preventing catastrophic failures and enhancing operational safety.

The device also excels in its low power consumption, particularly in standby mode. This is increasingly important to meet stringent international energy efficiency regulations. Its precise control loops ensure stable output voltage regulation, even under fluctuating load conditions, which is vital for powering sensitive industrial electronics.

Typical applications are vast and include:

Industrial motor drives and control systems.

Power supplies for automation equipment and robotics.

Charging systems for electric vehicles and industrial batteries.

Telecom and server infrastructure power modules.
