The VIPER20A-22-E is a special type of AC/DC converter, falling under the category of offline switchers. It has a wide operating temperature range and is suitable for applications such as automotive, industrial, and domestic, where extreme temperature conditions may be present. The device is capable of providing up to 22A of output current with a peak power rating of 20W. The VIPER20A-22-E is designed for applications such as power supplies, lamp ballasts, and lighting ballasts, among others.

The VIPER20A-22-E AC/DC converter features a constant-voltage (CV) output, combined with a constant-current (CC) output. This ensures that the output current remains constant, even if the input voltage changes. The outputs are equipped with a low ripple voltage and overvoltage protection, as well as a thermal shutdown for protection against over-temperature conditions and overloads. The device has a minimum start-up time, making it ideal for applications that require an instant start-up, such as street lamps and signs.

The device operates in both an open drain and a totem pole configuration, maximizing the flexibility of the system design and the utilization of the AC/DC converter in a wide range of applications. The unique combination of load protection and high efficiency makes the VIPER20A-22-EAC/DC converter one of the most reliable off line AC/DC converters available.

The design of the VIPER20A-22-E AC/DC converter makes use of an active PFC (Power Factor Correction) circuit, designed to provide a lower input current and a high power factor. This improves the utilisation of the input power, resulting in an overall improvement of the converter’s efficiency. The design of the AC/DC converter is further optimised with an innovative Thermal Profile Control (TPC) circuit, which modulates the voltage or current based on the temperature of the device’s components. The combination of the PFC and TPC circuits significantly improve the efficiency of the device.

The VIPER20A-22-E AC/DC converter also features a built-in Digital Measuring Module (DMM), which can measure the output voltage and current. This allows the device to accurately monitor the performance of its outputs. The built-in testing and monitoring functions of the device add to the overall reliability of the device, making it the ideal AC/DC converter for safety sensitive applications. The device also offers low standby power consumption, adding to its overall efficiency.

In summary, the VIPER20A-22-E AC/DC converter is a high-performance, reliable and efficient device, suitable for a variety of AC/DC applications. Its innovative PFC, DMM and TPC circuits provide improved power efficiency and output reliability, making the device the ideal choice for applications such as power supplies, lamp ballasts, and lighting ballasts. Further features such as its low standby power consumption, its overvoltage protection, and its wide operating temperature range make the VIPER20A-22-E AC/DC converter an ideal choice for safety sensitive applications.
