The DC2268A-B is a power supply evaluation board for offline AC/DC and DC/DC switching applications. It is designed to evaluate the performance of power supply switchers targeted for a wide range of applications from commercial to industrial and consumer applications. It provides a complete evaluation environment with a high-level of protection, accuracy, and flexibility.

This evaluation board is specifically designed for high-power DC to DC and AC to DC converters. It consists of a DC2268A power supply board and a DC2268B power control board. The DC2268A is a switch-mode power supply board with a variety of inputs such as a universal input voltage selection (from 100V to 600V AC), a limited-short-circuit current limit, and an adjustable power-saving circuit. The DC2268B power control board provides a range of adjustable features such as variable over-current protection, output current and voltage regulation, and power failsafe protection. The DC2268A-B provides an easy-to-use and powerful solution for testing a range of AC/DC and DC/DC switching power supplies.

The evaluation board features an isolated galvanically isolated up to 4kV, low-voltage to high-voltage operation, low noise, high efficiency, wide voltage and current ranges, and a wide range of safety features. It also provides a wide range of features such as over-voltage and under-voltage protection, over-temperature protection, short-circuit protection, output current regulation, output voltage regulation, and power fail safe protection. The DC2268A-B also provides two optional power control heatsinks for increased cooling. Furthermore, it is capable of providing up to 30A output current, and it can operate with either DC or AC input.

The DC2268A-B uses a combination of synchronous rectifiers and linear regulators to achieve high efficiency with low switching noise and low output ripple. The synchronous rectifiers allow for fast response, low heat dissipation, and high efficiency conversion between input and output. The output of the DC2268A-B can be adjusted by controlling the DC current flowing through the synchronous rectifiers. The DC2268B power control board is used to adjust the current load on the power switch and adjust power-saving features.

The board features low electromagnetic interference (EMI) with EMI-compliant EMC test results. It also meets the EN61000-3 series international standards for transients, as well as the stringent CSA standards. The board is tested to create a low-noise environment for power supplies, including audio and video equipment. The DC2268A-B is also compliant with the latest UL, CSA, and CE standards.

The DC2268A-B evaluation board provides an ideal environment for testing and evaluating power supplies for a wide range of applications. It is capable of providing high accuracy, flexibility, and protection to a variety of loads and can be used to develop and evaluate switchers for both commercial and industrial applications. The wide range of features available makes it suitable for a wide range of applications from audio and video equipment to consumer electronics.
