The EVB-EP5357HUI is an evaluation board, categorized as an “off-line” DC/DC converters & AC/DC power supply. It enables engineers to quickly evaluate, prototype, and develop new power supply designs or applications. The board is based on the the versatile EP5357HUI PWM controller, which is suitable for AC/DC power supply and DC/DC switching converter applications. With its excellent performance and features, together with excellent pricing, the EVB-EP5357HUI is an excellent choice for product designers and system application engineers.

The EVB-EP5357HUI is specifically designed for use in off-line applications, including AC/DC adapters, power supplies, chargers, DC/DC converters, and more. The board contains a host of features that greatly facilitate the design process. These features include a comprehensive set of protection functions such as over temperature, short circuit, input under voltage, and output over voltage protection. Furthermore, its built-in PI control loop solution enables it to deliver a stable and reliable output over a wide range of input and load conditions. The board is shipped with all required components, reducing the time required to design and test power supplies.

The EP5357HUI works by using pulse width modulation (PWM) control technology. The PWM technique is used as it allows for a wide range of input and output voltage combinations, ensuring the optimal output power is achieved. The board utilizes cycle-by-cycle peak current limit control, where the PWM controller looks at the output voltage every single switching cycle and adjusts the current limit accordingly, which results in better stability and higher efficiency. Additionally, the controller can accommodate a wide range of operating frequencies, from 35kHz up to 275kHz.

The EVB-EP5357HUI ships with two separate reference designs, one for flyback converters and one for forward converters. The board is designed to operate over the entire range of input voltage, allowing the user to quickly evaluate the most suitable input voltage. It also supports the PI control loop solution to ensure that the power supply maintains very stable output voltage. Furthermore, the board supports output over-voltage protection, temperature protection, overload protection, and phase-drop protection, providing both safety and reliability.

In conclusion, the EVB-EP5357HUI evaluation board offers numerous advantages over other solutions, and is an excellent choice for evaluation, prototyping, and development of new power supply designs and applications. It has a comprehensive set of features, it supports wide input and output voltage combinations, and it offers excellent performance at competitive pricing. With its support for PI control loop solution, along with many protection functions, it is a reliable and robust solution that can be used in a variety of applications.
