The BD9E300EFJ-EVK-001 evaluation board is designed for DC/DC and AC/DC (off-line) switching mode power supplies (SMPS) and is integrated with a wide range of features to suit the needs of an industrial application. The evaluation board is based on a BD9E300E power supply controller from Emphatec and features a wide range of protection and control functions. The BD9E300EFJ-EVK-001 is a great solution for applications that require high-efficiency, high-current, and high-voltage power supplies.

The BD9E300EFJ-EVK-001 is designed to provide reliable, efficient, and cost-effective operation in varying temperatures and environmental conditions. It provides protection against various faults including high-voltage, overcurrent, overvoltage, and thermal overload. The board also features a 3-phase PFC circuit and a phase-shifted PFC circuit, allowing for more efficient power conversion and improved load operation. The BD9E300EFJ-EVK-001 also includes a number of monitoring and protection features, including a power good output, programmable soft start, programmable hiccup shutdown, and programmable output voltage limit.

The BD9E300EFJ-EVK-001 features dual operating modes, continuous conduction mode (CCM) and discontinuous conduction mode (DCM). In CCM, the controller operates with a regulated on-time and off-time signal, which provides cost effective and reliable operation over a wide range of loads. In DCM, the controller operates with a regulated duty cycle, allowing for improved efficiency and improved load performance. Both modes support a wide range of power supply designs from 2.2W to 500W.

The BD9E300EFJ-EVK-001 is designed to operate in EC Fan Control (EFC) and Overvoltage Protection (OV) modes. In EFC mode, the controller is able to detect low speed fan faults and provide a control signal to the fan, assuring efficient operation even in extreme temperature conditions. In OV mode, the controller will detect if the output voltage of the power supply exceeds a predetermined level and shut down the supply in order to protect downstream components.

The BD9E300EFJ-EVK-001 also features a comprehensive temperature protection scheme, which is designed to protect the power supply from overheating, providing enhanced reliability and longer life. This feature allows the supply to sense the temperature of various components and shut down the power supply if the temperature exceeds the set threshold.

In short, the BD9E300EFJ-EVK-001 evaluation board is an efficient, reliable, and cost-effective solution for a wide range of off-line switching mode power supplies (SMPS). It provides a number of features that make it well-suited for operation in harsh environmental conditions. Its advanced protection features ensure safe operation and long-term reliability. The BD9E300EFJ-EVK-001 is a great choice for applications that require high-current, high-voltage, and high efficiency power supplies.
