Infineon PEB3264HV4: 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 PEB3264HV4 stands out as a highly integrated power supply controller designed specifically for high-voltage and high-power applications. This advanced controller combines state-of-the-art technology with rugged reliability, making it an ideal cornerstone for industrial power supplies, motor drives, and renewable energy inverters.

At its core, the PEB3264HV4 is engineered to manage high-voltage startup and operation, significantly simplifying the design of the critical initial power-up phase. It features an integrated high-voltage startup cell, which allows it to be directly connected to the rectified mains voltage, eliminating the need for a separate auxiliary power supply for startup. This not only reduces the external component count and board space but also enhances overall system reliability.

A key strength of this controller is its support for resonant half-bridge topologies, particularly the LLC resonant converter. This architecture is renowned for its high efficiency, as it enables soft-switching operations that minimize switching losses and electromagnetic interference (EMI). The PEB3264HV4 provides precise control over this process, ensuring optimal switching transitions that are crucial for achieving peak efficiency in high-power designs. Furthermore, it incorporates advanced protection and safety features, including over-current protection (OCP), over-voltage protection (OVP), and over-temperature protection (OTP). These integrated safeguards are vital for ensuring the longevity and safe operation of industrial equipment in harsh environments.

The device also offers significant design flexibility. It supports a wide operating frequency range and provides adjustable control parameters, allowing engineers to fine-tune performance for specific application requirements. This programmability, combined with its high level of integration, accelerates development cycles and helps create more compact and cost-effective end products.
