Introduction

The AD5012N3LM AC/DC Desktop, Wall Adapters are intended to provide reliable power for portable computing applications. These adapters come in a variety of models and provide a variety of output voltages and currents. In this article, we will discuss the application field and working principle of the AD5012N3LM AC/DC Desktop, Wall Adapters.

Application Field

The AD5012N3LM AC/DC Desktop, Wall Adapters are designed to power a variety of portable computing applications including laptops, netbooks, cell phones, digital cameras, and other portable electronic devices that require a DC voltage in the range of 3.3 V to 18.5 V. The adapters come in three models with input voltage ranges from 100 VAC to 240 VAC. The adapters feature a universal input voltage range that allows them to be used in any region in the world.The adapters feature a variety of output voltages and currents to meet the needs of different devices. The AD5012N3LM-6 model has a maximum output current of 3.6 A and a maximum output power of 18.5 W. The AD5012N3LM-9 model has a maximum output current of 4.75A and a maximum output power of 25.5 W. The AD5012N3LM-12 model has a maximum output current of 6.0 A and a maximum output power of 32.4 W.

Working Principle

The AD5012N3LM AC/DC Desktop, Wall Adapters use a switching power supply topology. This type of power supply topology is more efficient than traditional linear power supplies since it only draws power when required.The switching power supply topology uses an AC/DC converter to convert the AC voltage of the wall outlet into a DC voltage. The DC voltage is then sent to a power transformer that steps the voltage down to the desired level and sends it to the output device.The next stage of the switching power supply is the control circuitry. This control circuitry regulates the output voltage and current. It consists of an oscillator, rectifier and filter, and a voltage regulator. The oscillator creates the switching signal and the rectifier and filter filters the DC output voltage. The voltage regulator uses feedback from the output to regulate the output voltage and current.

Conclusion

The AD5012N3LM AC/DC Desktop, Wall Adapters are designed to provide reliable power for a variety of portable computing applications. The adapters feature a universal input voltage range that allows them to be used in any region in the world. The adapters use a switching power supply topology that is more efficient than traditional linear power supplies. The control circuitry is used to regulate the output voltage and current.
