The ADM00427 evaluation board is a DC/DC & AC/DC (Off-Line) SMPS integrated circuit designed by Analog Devices, Inc. It is a highly efficient, cost effective, energy saving device suitable for a wide range of applications.

The board is based on an internal high speed power conversion controller, which can provide a variable output voltage and current to suit the application requirement. It has an adjustable constant frequency, adjustable output current, and adjustable DC output voltages. The controller provides a wide range of features and regulation suitable for most applications.

The power stage supports high frequency synchronous rectification which can support higher efficiency for the power converter. This feature allows the ADM00427 to provide optimum performance for a wide range of input voltages and load conditions. The ADM00427 can also be programmed to support a wide range of pulse width modulation (PWM) frequency to match the application requirements.

The evaluation board also features a low threshold active bleed circuit, which can reduce power dissipation. This feature improves the overall system efficiency by minimizing the amount of power dissipated by the power converter. The ADM00427 features built in protection circuits which will shut down the board if the output current flows out of specification or the input voltage reaches an unsafe level.

The ADM00427 features a wide input voltage range of 12.5V to 58V, and can support a wide range of output voltage and current requirements from 3.3V to 36V and up to 20A. The evaluation board also features a maximum efficiency rating of over 90%. The dimensions of the board are 8.25"x2.25"x1.08" and it weighs 0.7 lbs.

The working principle of the ADM00427 evaluation board is based on a switching power conversion technology, which provides high efficiency power conversion from the input source to the output load. The switching process uses a converted output voltage and current, switching frequency, duty cycle time, and an internal control loop to regulate the output voltage and maintain the desired output current.

The evaluation board supports constant frequency and/or variable frequency operation. In variable frequency mode, the board can be set up to automatically adjust the switching frequency depending on the output current and load conditions. This helps to improve the efficiency of the power converter and reduce power dissipation.

The ADM00427 evaluation board can be used in a wide range of applications such as industrial equipment, led lighting, medical equipment, telecommunications equipment, and servers. It is an easy to use and highly efficient way to power a wide range of applications.
