STMicroelectronics VIPER06HS High Voltage Converter

The VIPER06HS from STMicroelectronics is a high-performance, fixed-frequency offline converter that combines a robust and compact design with efficiency and reliability. Specifically engineered for switched-mode power supplies (SMPS), the VIPER06HS is an excellent choice for power applications requiring a low-power, high-voltage converter.

This innovative device operates at a fixed 60 kHz switching frequency with a jittered mode to achieve lower EMI and includes a high-voltage startup circuit, which allows for a quick and efficient power-up. Its integrated 800 V avalanche-rugged power MOSFET ensures that the VIPER06HS can withstand high energy spikes and harsh operating conditions, making it suitable for a wide range of industrial and consumer applications.

Featuring multiple protection features, the VIPER06HS is designed to safeguard against overcurrent, overvoltage, overload, and short-circuit conditions. This enhances system reliability and provides designers with peace of mind when integrating this component into their power supply designs. The thermal shutdown with hysteresis also ensures safe operation by preventing overheating and potential damage to the device and the system it powers.

The VIPER06HS is also optimized for efficiency, with a low standby power consumption of less than 30 mW at 265 VAC, making it compliant with energy-saving regulations such as Energy Star or the European Code of Conduct. An additional benefit is its burst-mode operation, which enables the power supply to achieve low power consumption under light-load conditions.

With its extended input voltage range, the VIPER06HS can handle variations in the power supply without compromising performance. This makes it a versatile choice for a variety of AC/DC converters, particularly those used in auxiliary power supplies, home appliances, power adapters, and other low-power applications where energy efficiency and compactness are critical.

Overall, the STMicroelectronics VIPER06HS is a robust and reliable high-voltage converter that offers an optimal balance of performance, protection, and power efficiency, making it a valuable component for designers looking to create compact, energy-efficient power solutions.
