The VIPER22A by STMicroelectronics is a compact, high-performance monolithic switching converter that is part of the VIPerPlus family. This integrated circuit is designed to provide a cost-effective solution for offline switch-mode power supplies (SMPS) with a minimal external component count. It is particularly well-suited for applications requiring a power range of up to 12W.

One of the standout features of the VIPER22A is its integrated PWM controller combined with a 730V Power MOSFET, offering enhanced reliability and robustness. The device operates at a fixed 60 kHz switching frequency, allowing for a compact design with small-sized passive components. This makes it ideal for space-constrained applications.

The VIPER22A is equipped with several built-in protections that ensure the safety and longevity of both the converter and the powered application. These include overvoltage protection (OVP), overload protection (OLP), and thermal shutdown with automatic restart. Additionally, the device features low standby power consumption, which is crucial for energy-saving in standby modes.

With a wide input voltage range, the VIPER22A can handle variations in the power supply, making it versatile for various AC input applications. Its flexibility is further enhanced by its ability to be used in different topologies, such as flyback or buck converters, depending on the specific requirements of the application.

Designed for adaptability, the VIPER22A can be utilized in an array of devices and systems, including adapters, chargers, standby power supplies, and auxiliary supplies. Its ease of use, combined with the support and reliability offered by STMicroelectronics, makes the VIPER22A a go-to choice for designers looking to create efficient and cost-effective power solutions.
