Principle:

This AC DC Desktop and Wall Adapters is based on the principle of AC to DC conversion, which is mainly composed of input and output circuits and switching power supply. The AC power can be changed into DC power after rectification, filtering, and voltage adjustment on the input side, and then the high frequency switch is used to output the satisfying DC power.The device is based on the latest topology, Synchronous Rectification Buck. Efficient, reliable operation of the converter is achieved by a Step-Down Switching Buck topology and an optimized design. The isolation switch components are used to complete the power conversion process, which includes the basic rectification, filter, and frequency conversion processes, and minimize cost. The design of MENB1020A1803N01 adopts extremely high performance components, plus optimized circuit design, which can reduce the electrical losses of components and maximize power efficiency. The device also includes a high-performance voltage tracking, voltage clamping, and a wide output voltage range circuit, increasing the output power range and ensuring the reliable operation of the product.

Benefits:

Compared with other AC DC Desktop and Wall Adapters, the advantages of MENB1020A1803N01 are as follows:1. High power efficiency: With the latest Synchronous Rectification Buck technology, the power efficiency can be up to 95%. Under the conditions of full load and nominal input voltage, the efficiency meets EISA 2007/DoE Level VI Standard, providing great efficiency without wasting energy.2. Safety and reliability: This AC DC Desktop and Wall Adapters is designed for keeping the changing output voltage range very small. The tight voltage tolerance of the output optimizes the safety, and using a protected diode to eliminate "Flyback" can make it more reliable.3. High performance: Built-in features, such as ripple suppression and zero-voltage /zero-current switching (ZVS /ZCS), reduce the stress of the system components and improve good EMI performance.

Conclusion:

For AC DC Desktop and Wall Adapters, MENB1020A1803N01 is the best choice to meet your application needs. It has the advantages of high efficiency, low cost, high reliability, safety and good EMI performance, which is enough to prove that it is an ideal power supply component for small electronics, phone charger or remote power.
