EVB-EN29A0QI is a cost-effective evaluation board which is used for power conversion applications. It is one of the popular evaluation boards in DC/DC & AC/DC (Off-Line) SMPS. This evaluation board leverage NXP’s EN29A0QI high frequency offline controller to design a 10 Watts solution. This solution operates efficiently while providing up to 10 Watts of output power.

The EVB-EN29A0QI board can be used for various off-line SMPS applications in a wide voltage range by connecting two external resistors. This board is applicable for power supplies ranging from 5 to 24 V DC input voltage. Some of the applications for which this board is suitable are used in wall mounted adapter, external power supplies, AC/DC adapters and so on. This evaluation board also helps in analyzing the performance of the EN29A0QI controller, and design and test time for custom fixed frequency off-line applications is significantly reduced.

The EVB-EN29A0QI board features wide input voltage range of 90V 295V AC and can output 5.1V-38V DC with over current and short circuit protection. In addition, it has an on-board sense resistor for current limiting and overload protection. The board has a low-noise operation and can operate at frequencies up to 30kHz with a low harmonic distortion. Due to these features, the EVB-EN29A0QI board provides superior performance in a wide variety of dc-dc and ac-dc applications.

EVB-EN29A0QI board works based on the principle of power conversion. It uses the EN29A0QI high frequency offline controller to provide an efficient AC-DC conversion. The power conversion takes place through the processes of rectification, conversion, and regulation. During rectification, the power is converted from AC input to DC output, and during conversion, the voltage is changed from DC to AC. Finally, during regulation, the output voltage is regulated to the desired level.

The EVB-EN29A0QI board is a great tool for evaluating the EN29A0QI controller for a variety of applications. This board not only helps to reduce design and test time significantly, but also provide superior performance in a wide range of applications. It is well suited for design engineers and power enthusiasts who are looking for efficient and cost-effective power electronics solutions.
