The VIPER22ADIP-E is a type of voltage regulator, more specifically a Pulse Width Modulation (PWM) off-line switch mode current feed forward (SCFF) voltage regulator. It is part of a family of low-cost, high performance off-line switch mode AC/DC converters from STMicroelectronics. The VIPER22ADIP-E is designed to provide a very efficient and cost-effective solution for applications requiring regulation of output voltage up to 600 V and a wide input range.

The VIPER22ADIP-E is a single-phase device that is housed in a standard dip package. It is a combination of an advanced current mode PWM controller, a forward converter arrangement and an additional SCFF structure. This structure allows the control IC to utilize feedback signals to control output power. It also offers a very low EMI performance level and is protected against short circuit, over voltage and overtemperature. Additionally, the package includes a secondary side synchronous rectifier, providing fast recovery and low reverse current.

The VIPER22ADIP-E operates using an input range of between 17V and 600V, making it well suited for applications requiring wider input ranges such as DC/DC conversion for distributed power networks. The operating frequency of this device can be varied between 20kHz and 130kHz, thus making it ideal for applications where a wide output adjustments is required. Further, the PWM signal control provides a constant current source for increased output performance, as compared with conventional equivalent systems. In addition, it has a very low stand-by power requirement.

One of the major advantages of the VIPER22ADIP-E is its superior protection features. It is protected against short circuit, over voltage and overtemperature, as well as being protected against overvoltage pulses. In addition, it includes a unique feature that allows the user to monitor the output power and the secondary side synchronous rectifier current at a single point. This provides an increased level of safety, allowing the user to detect a potential problem before it can cause damage.

The VIPER22ADIP-E is an ideal solution for AC/DC conversion in distributed power networks. It offers performance, low cost and protection features that make it one of the most attractive AC/DC converters available. Its wide input range combined with a low EMI level make it very attractive for applications requiring high efficiency and low noise operation. It is a highly reliable and cost effective solution for applications where a fast response to changes in the input supply is required.
