STMicroelectronics VIPER28HDTR - High Voltage Converter

The VIPER28HDTR from STMicroelectronics is a state-of-the-art high voltage converter that is part of the VIPerPlus family. This device is specifically designed to meet the needs of low power applications, providing a cost-effective and energy-efficient solution for AC/DC conversion. The VIPER28HDTR integrates a PWM controller and a 730V avalanche-rugged power MOSFET, making it ideal for a wide range of applications including adapters, power supplies for consumer electronics, and auxiliary supplies for white goods and industrial systems.

One of the key features of the VIPER28HDTR is its ability to operate over a wide supply voltage range, ensuring consistent performance even under varying power conditions. This makes it highly versatile for global products that must comply with different electrical standards. Additionally, the device boasts an extremely low power consumption under no-load conditions, contributing to energy savings and compliance with modern green energy standards.

The VIPER28HDTR incorporates advanced protection features to ensure the safety and reliability of the end application. These include overvoltage protection (OVP), overcurrent protection (OCP), thermal shutdown, and hysteresis. The built-in soft-start function ensures a gradual increase in output voltage, which prevents abrupt changes that could potentially damage sensitive electronic components.

For design flexibility, the VIPER28HDTR offers frequency jittering, which helps in reducing electromagnetic interference (EMI), a critical consideration for passing stringent EMI regulations. The device also supports multiple topologies, such as flyback, buck, and buck-boost, providing designers with the freedom to choose the most suitable configuration for their specific application.

In summary, the VIPER28HDTR from STMicroelectronics represents a robust and flexible solution for power conversion needs. Its integration of a high-voltage MOSFET with a PWM controller, coupled with its energy-saving features and comprehensive protection mechanisms, makes it a smart choice for manufacturers looking to enhance the performance and reliability of their power supply designs.
