STMicroelectronics VIPER20-22-E SMPS Power Converter

The VIPER20-22-E from STMicroelectronics is a high-performance, fixed-frequency SMPS (Switched-Mode Power Supply) power converter that integrates a PWM (Pulse Width Modulation) controller and a 200V vertical power MOSFET in one compact package. This device is part of the VIPerPlus family and is designed to deliver an efficient, reliable, and cost-effective solution for a wide range of power supply applications.

The VIPER20-22-E is capable of providing up to 22W of output power when used in an open-frame configuration, and it supports both isolated and non-isolated topologies. This versatility makes it an ideal choice for applications such as adapters, power supplies for consumer electronics, auxiliary power supplies for home appliances, and industrial control systems.

Key features of the VIPER20-22-E include an 800mA current capability, an extended input voltage range, and multiple protection mechanisms. The device offers overvoltage, overload, and thermal shutdown protections, ensuring safe operation under a variety of conditions. The built-in soft-start function minimizes stress on the power supply during start-up, contributing to the longevity of the system.

The VIPER20-22-E also boasts low standby power consumption, which is particularly important for energy-saving regulations compliance. Its quiescent current is less than 5mA, which helps in achieving excellent efficiency and reduces power losses when the system is in standby mode.

For designers and engineers, the VIPER20-22-E simplifies the design of robust and compact power supplies, thanks to its integrated features and minimal external component requirements. The device is available in a DIP-8 and SO-16 package, providing flexibility for various PCB layouts and space-constrained applications.

Overall, the VIPER20-22-E is a testament to STMicroelectronics' commitment to providing advanced power management solutions that meet the evolving needs of modern electronic systems. Its integration of a controller with a high-voltage power MOSFET, along with its comprehensive protection features and energy-efficient performance, make it a prime choice for developers looking to create reliable and high-performance power supplies.
