AC-DC converters are used to convert AC power sources to DC voltages. The JWT75522/R is an AC-DC converter that converts alternating current to direct current with an efficiency of up to 90%. It is designed to operate in a wide input range from 90-265VAC and operates at temperatures of -40 to +85°C.

The JWT75522/R contains a built-in EMI filter to reduce EMI noise and provide a clean DC output voltage. The built-in protection features of the converter ensure reliable operation. The over-voltage, over-current, over-temperature, and short-circuit protection circuits prevent damage to the system. The power factor correction (PFC) circuit improves the power factor of the input current.

The JWT75522/R is a high-efficiency single-stage AC-DC converter with a wide input voltage range. It converts AC input power to DC through a full-bridge rectifier followed by a switching regulator. The switching regulator contains a high-frequency transformer, MOSFETs, and a controller IC. The MOSFETs switch rapidly at a frequency of 27MHz to allow high power conversion efficiency.

The controller IC provides the control signal for the switching MOSFETs. It also provides feedback signals to maintain a constant DC output voltage. The controller contains an EMI filter circuit to reduce conducted EMI noise and improve the EMC performance of the converter. The built-in PFC circuit also helps to reduce the power discrepancy between the input and output.

The JWT75522/R is suitable for applications such as LED lighting, motor control, industrial equipment, and portable electronic devices. It provides excellent power conversion efficiency and a clean DC output voltage. Its wide range of operating temperatures and protection features make the JWT75522/R a reliable choice for AC-DC conversion.
