PEB3265HV1.3: Infineon's High-Voltage Power Supply Controller

In the realm of power electronics, efficiency, reliability, and integration are paramount. Addressing these critical demands, Infineon Technologies introduces the PEB3265HV1.3, a highly advanced high-voltage power supply controller IC designed for demanding applications. This controller stands out as a cornerstone for next-generation switch-mode power supplies (SMPS), offering a blend of performance and protection that empowers designers to create more compact, efficient, and robust systems.

At the heart of the PEB3265HV1.3 is its ability to handle high-voltage inputs directly. It integrates a robust startup cell, allowing it to operate from a line voltage up to 725 V, which significantly simplifies the design by reducing the need for external auxiliary components. This high level of integration is a key advantage, enabling a more streamlined bill of materials (BOM) and a smaller overall footprint for the power supply unit.

The controller is engineered for resonant half-bridge topologies, particularly LLC converters, which are renowned for their high efficiency across a wide load range. It features precise frequency control to manage the power conversion process optimally. The IC includes a comprehensive suite of protection features, such as over-current protection (OCP), over-voltage protection (OVP), and over-temperature protection (OTP), ensuring safe operation under fault conditions and enhancing the overall reliability of the end product.

Furthermore, the PEB3265HV1.3 supports burst mode operation at light loads, which is crucial for minimizing standby power consumption and meeting stringent energy efficiency regulations like the European CoC V5 tier 2 and ENERGY STAR. Its programmable control parameters offer designers the flexibility to fine-tune the power supply's behavior for specific application needs, ranging from industrial systems to high-end consumer electronics.

ICGOODFIND: The Infineon PEB3265HV1.3 represents a significant leap in power supply control technology. Its high integration level, superior protection mechanisms, and support for efficient resonant topologies make it an exceptional choice for engineers aiming to develop power supplies that are not only powerful and reliable but also align with modern energy efficiency standards.
