Product Description
The STMicroelectronics VIPER319HDTR AC/DC Converter is a high-voltage power management integrated circuit designed with an embedded 800 V avalanche rugged power MOSFET and a PWM current-mode controller. This device enables efficient AC to DC conversion with a maximum output current of 3 A and features a low switching frequency of 15 kHz to optimize electromagnetic interference and efficiency. It supports a wide input voltage range from 85 V minimum to 265 V maximum, allowing robust operation under varying supply conditions.
This converter utilizes flyback topology with an 80% maximum duty cycle, providing a reliable solution for isolated power supplies commonly used in home appliances, industrial automation, and home automation systems. The device includes built-in protections for overvoltage and undervoltage events with customizable intervention thresholds via dedicated pins, enhancing system safety and reliability.
Additional features include ultra-low input power consumption that minimizes standby losses and a built-in soft-start mechanism that prevents inrush current surges improving overall system stability and longevity. The compact SO-16N package, with dimensions 9.9 mm length, 1.75 mm width, and 6 mm height, is suitable for surface mounting in dense PCB layouts.
Operational temperature range from -40°C up to 150°C ensures suitability for demanding industrial and commercial environments. The device is RoHS compliant, adhering to environmental safety standards.
