Introducing the VIPER38LDTR from STMicroelectronics

The VIPER38LDTR is a cutting-edge, high-performance off-line converter from STMicroelectronics, designed to meet the rigorous demands of power supply applications. This device is part of the VIPerPlus family, which is renowned for its energy-efficient solutions and robustness in a variety of power conversion scenarios.

At the heart of the VIPER38LDTR's functionality is its 800 V avalanche-rugged power section, a PWM operation at 60 kHz with a frequency jittering feature for lower EMI, and multiple protection features that ensure the reliability and longevity of the end application. The converter integrates a high-voltage startup circuit that allows a very quick startup without the need for external components, which is particularly advantageous in reducing the overall bill of materials.

The VIPER38LDTR offers a current mode PWM controller and a 800 V power MOSFET in one package, enabling compact designs with minimal external components. This integration is crucial for applications that require a small form factor without compromising on power efficiency and performance.

Protection features of the VIPER38LDTR include thermal shutdown, overvoltage, overload, and short-circuit protection, which safeguard the device and the system it powers. These features not only prevent damage but also contribute to the safety of the end-user by ensuring the power supply operates within safe parameters.

With its built-in soft-start capability, the VIPER38LDTR ensures a gradual increase in the output voltage, which minimizes the stress on the system during the startup phase. This feature is particularly useful in preventing inrush current-related issues and extending the life of the power supply.

The VIPER38LDTR is a versatile solution suitable for a wide range of applications, including adapters, power supplies for consumer electronics, auxiliary supplies for home appliances, and industrial control systems. Its robustness and high level of integration make it an ideal choice for designers looking to create efficient, reliable, and cost-effective power solutions.

STMicroelectronics has a reputation for providing high-quality semiconductor products, and the VIPER38LDTR is no exception. It is a testament to the company's commitment to innovation and excellence in the field of power management technology.
