STEVAL-ISA097V1 - 2 kW fully digital AC-DC power supply (PFC and LLC) with STNRGPF01 and SLLIMM-nano

The STEVAL-ISA097V1 from STMicroelectronics is a state-of-the-art power supply solution that integrates advanced power factor correction (PFC) and LLC resonant converter topologies to deliver a highly efficient, fully digital AC-DC power supply. Designed to address the needs of high-performance applications, this 2 kW power supply board is part of ST's evaluation series that showcases the capabilities of the STNRGPF01 digital PFC controller and the SLLIMM™-nano intelligent power module.

With its robust design and cutting-edge technology, the STEVAL-ISA097V1 provides an excellent platform for developing and testing power supply systems for a wide range of applications, including servers, telecom, and industrial equipment. The board is engineered to optimize energy savings and reduce overall system cost by leveraging the digital control capabilities of the STNRGPF01, which allows for precise power factor correction and efficient load management.

The STEVAL-ISA097V1 features a two-stage approach, starting with a PFC stage that ensures compliance with international power quality standards by correcting the input power factor to near unity. Following this, the LLC resonant converter stage provides a regulated output voltage with high efficiency and low electromagnetic interference (EMI), making it suitable for noise-sensitive environments.

Key features of the STEVAL-ISA097V1 include:

• High power density and efficiency due to fully digital control
• Advanced STNRGPF01 digital PFC controller for accurate power factor correction
• SLLIMM™-nano intelligent power module for high switching performance
• Comprehensive protection features including overvoltage, overcurrent, and overtemperature protection
• Compliance with international power quality standards
• Flexible and configurable design for a variety of end applications

Developers can take advantage of the STEVAL-ISA097V1's features to accelerate the design cycle and bring high-efficiency power supply products to market faster. The evaluation board is supported by ST's extensive technical documentation, design tools, and software, providing a comprehensive development environment for power supply design engineers.
