STMicroelectronics VIPER12ADIP - Low Power Offline Switched-Mode Power Supply Primary Switcher

The VIPER12ADIP is a high-performance, low-power, offline switched-mode power supply (SMPS) primary switcher integrated circuit designed by STMicroelectronics. It is housed in a DIP-8 (Dual In-line Package) and is part of the VIPer™ Plus family, which is known for its ability to provide cost-effective and compact power solutions. This product is specifically tailored for applications requiring an AC/DC converter with a tight output regulation and a power range up to several tens of watts.

With an integrated 60 kHz fixed-frequency oscillator, the VIPER12ADIP minimizes the number of external components, which is beneficial for space-constrained applications. The device features a high-voltage startup circuit that allows the quick activation of the chip from the rectified mains voltage, ensuring a prompt response when power is needed.

The VIPER12ADIP is equipped with multiple protection features to ensure the safety and longevity of the power supply and the end application. These include overvoltage protection (OVP), overload protection (OLP), and thermal shutdown (TSD) with automatic restart. The built-in pulse skip modulation also contributes to improved efficiency at light loads, which is essential for meeting energy-saving standards.

This versatile power switcher is suitable for a wide range of applications, such as auxiliary power supplies for home appliances, standby power supplies for TV or monitors, and power supplies for battery chargers, adapters, and audio/video equipment. Its robustness and reliability make it a preferred choice for designers who require a proven solution for their low-power SMPS designs.

The VIPER12ADIP's ability to operate over a wide input voltage range, from 85V to 265V, makes it ideal for global products without the need for any adjustments. Additionally, its low power consumption in standby mode helps consumer products comply with the latest energy-saving regulations, making it an environmentally friendly choice for power supply design.

Overall, the VIPER12ADIP from STMicroelectronics is a compact, efficient, and reliable solution for a variety of power supply applications, offering ease of design and a high level of integration to help reduce time to market.
