STMicroelectronics VIPER17LD - High-Voltage Converter

The VIPER17LD from STMicroelectronics is a robust, high-voltage converter that integrates a dedicated PWM (Pulse Width Modulation) controller and an 800 V avalanche-rugged power MOSFET. Designed for flexibility and efficiency, the VIPER17LD is a prime choice for power supply applications that demand compact size, strong performance, and reliability.

With its wide input voltage range, the VIPER17LD is well-suited for applications that must operate in various power conditions, making it ideal for both industrial and consumer electronics. The device enables designers to create efficient switch-mode power supplies with a minimal external component count, thanks to its integrated features such as a high-voltage startup circuit, a sense FET, and an error amplifier.

The VIPER17LD boasts multiple protection features that enhance system safety and longevity. These include overvoltage protection, overload protection, thermal shutdown with hysteresis, and a soft-start function to limit inrush current. These protections ensure that the device can handle tough conditions without sacrificing performance or risking damage to the power supply or the end application.

Efficiency is a key aspect of the VIPER17LD, which offers a low standby power consumption of less than 50 mW at 265 VAC with no load, thanks to its pulse frequency modulation at light load. This efficiency, combined with the device's power-saving features, makes the VIPER17LD an environmentally friendly option that can help in designing energy-saving power supplies.

The VIPER17LD comes in a compact SO-16N package, which is not only space-saving but also conducive for thermal management. This makes it an excellent choice for applications with limited PCB space that also require a high level of integration.

In summary, the STMicroelectronics VIPER17LD is a versatile and efficient high-voltage converter that offers a comprehensive set of features for the design of reliable and compact power supplies. Its integrated protections and energy-saving capabilities make it a smart choice for a wide range of power applications.
