STMicroelectronics VIPER20ASP - High-Voltage Converter

The VIPER20ASP from STMicroelectronics is a robust and versatile high-voltage converter that integrates a powerful PWM controller and a high-voltage MOSFET in a single package. This device is part of the VIPerPlus family, known for providing cost-effective and energy-efficient solutions for power supply designs. The VIPER20ASP is specially designed to meet the stringent demands of switch mode power supplies (SMPS) and is capable of driving up to 360 mA of current.

With its wide input voltage range, the VIPER20ASP is suitable for a variety of AC/DC applications, from industrial control systems to consumer electronics. The device offers a flexible solution for designers, thanks to its adjustable operating frequency, which can be set from 30 kHz to 60 kHz by connecting a resistor to the dedicated pin. This feature allows optimization of the size and performance of the power supply, balancing efficiency and EMI considerations.

The VIPER20ASP incorporates several protective features to ensure reliability and safety in operation. This includes overvoltage protection, thermal shutdown, and a soft-start function that prevents inrush current at startup. Additionally, the built-in error amplifier and the under-voltage lockout with hysteresis enhance the stability and performance of the power supply under varying load conditions and input voltages.

Constructed in a robust and compact Pentawatt HV package, the VIPER20ASP is designed to withstand the rigors of high-voltage environments while minimizing the PCB footprint. This makes it an excellent choice for space-constrained applications where efficiency and reliability are paramount.

Whether you are designing an off-line converter for a home appliance, an auxiliary power supply for an industrial system, or a power adapter, the VIPER20ASP offers a high degree of integration, reducing the number of external components required and simplifying the overall design process. With its combination of features, the VIPER20ASP stands out as a reliable and efficient solution for your power supply needs.
