STMicroelectronics VIPER17HDTR Product Overview

The VIPER17HDTR from STMicroelectronics is a high-performance, low-power offline switched-mode power supply (SMPS) primary switcher, designed to deliver constant output current and voltage. This device integrates a PWM controller and a 800 V avalanche-rugged power MOSFET, making it exceptionally suitable for AC/DC converters and LED driver applications.

With its wide input voltage range, the VIPER17HDTR is versatile and can be used in a variety of electrical environments. It is especially efficient in applications requiring a high level of reliability and power efficiency, such as home appliances, industrial control systems, and standby power supplies.

The VIPER17HDTR boasts several features that enhance its performance and safety. It includes a current-mode PWM controller which allows for simple external loop compensation and flexible EMI filter design. Its built-in protections, such as overload protection, overvoltage protection, and thermal shutdown with hysteresis, ensure the safety and longevity of both the device and the end application. Moreover, the VIPER17HDTR has a low standby power consumption of less than 50 mW at 265 VAC, making it an energy-efficient choice for eco-conscious designs.

Additional features like frequency jittering help in reducing electromagnetic interference, thereby simplifying the compliance with international EMI regulations. The VIPER17HDTR also supports burst mode operation, which further reduces power consumption during light-load conditions, making it ideal for applications that require low power in standby mode.

Offered in a compact SO-16N package, the VIPER17HDTR is designed to minimize the required PCB area, providing a space-saving solution for compact power supplies. Its robust design ensures a long operational life and consistent performance, making it a reliable choice for designers looking to create efficient and durable power supply systems.

In summary, the VIPER17HDTR from STMicroelectronics is a feature-rich, energy-efficient power conversion solution that is well-suited for a wide range of applications that demand high reliability and performance in a compact footprint.
