AC/DC converters are used to provide DC power from single-phase AC power sources, and the LWN1301-6EG is no different. It is a switched-mode power supply (SMPS) with a wide input voltage range, low ripple at full-load operation and low EMI generation. It is also capable of supplying high current output up to 6A.

The LWN1301-6EG is a low-cost 220VAC input, 12V/6A output switching power supply that is suitable for many applications. It has several features including active load sharing among multiple AC inputs, low output ripple, high efficiency, low standby loss and a wide operating temperature range. The power converter has a built-in over-current, over-temperature, reverse polarity and short-circuit protection, which ensures its safe operation.

The LWN1301-6EG is based on an avalanche MOSFET (A-MOSFET) switch and a synchronous rectifier. This SMPS circuit is designed to offer high efficiency, low noise, and good power factor. The A-MOSFET switch is used to control the voltage and the current to the output, while the synchronous rectifier is used to rectify the AC input to DC and regulate the output voltage and current. A full-bridge rectifier is utilized to convert AC power to full-wave DC power, making it suitable for applications requiring high-power output.

The LWN1301-6EG is implemented using a fixed frequency current-mode topology. This mode of circuit operation allows the converter to quickly respond to load variations and is also very efficient. The AC/DC converter has a wide input voltage range of 100-240VAC, allowing it to be used in a broad range of applications. Additionally, it has a wide output voltage adjustment range of 4.5 to 13.2V, making it suitable for most applications.

The SMPS circuit of the LWN1301-6EG has several advantages compared to linear power supplies, such as higher efficiency, better thermal performance, smaller size, and lower output ripple noise. Additionally, the LWN1301-6EG has a peak current limit feature that helps protect the circuit from over-current, and helps provide reliable performance. The power converter also has a start/no-load-state control circuit, which allows it to start up reliably from cold or hot start conditions.

The LWN1301-6EG is a highly reliable and cost-effective power supply suitable for a variety of applications. It has a wide input voltage range and low output ripple, and is capable of supplying up to 6A of current. Additionally, the power converter has an integrated EMI filter, which helps reduce EMI generated by the power supply. With its high efficiency, low standby loss, and active load sharing circuit, the LWN1301-6EG is an ideal choice for powering various industrial and consumer electronics.
