STMicroelectronics VIPER113LS: High-Voltage Converter

The VIPER113LS from STMicroelectronics is a cutting-edge, high-voltage converter designed for a wide range of applications, including power supplies and power adapters. This efficient, off-line switched-mode power supply (SMPS) controller features a rugged design and is capable of delivering optimal performance even under challenging conditions.

At the heart of the VIPER113LS is a pulse-width modulation (PWM) controller integrated with an 800 V avalanche-rugged power section, providing a compact solution that minimizes the need for external components. This integration not only simplifies the design process but also enhances the reliability of the final product, making it suitable for applications that demand high levels of dependability.

The device is well-suited for converters with a direct 800 V bus voltage, eliminating the need for an auxiliary winding. This feature, combined with its high-voltage capability, makes the VIPER113LS particularly useful for applications that require a simple, efficient, and cost-effective approach to power conversion.

One of the key advantages of the VIPER113LS is its built-in high-voltage startup circuit. This allows the converter to start up quickly and efficiently, reducing the standby power consumption and contributing to the overall energy efficiency of the system. Additionally, the device includes a jittered switching frequency, which helps to reduce electromagnetic interference (EMI), a critical consideration in today's electronically dense environments.

Other notable features of the VIPER113LS include overcurrent and overvoltage protections, thermal shutdown, and a low standby power consumption of less than 30 mW at 265 VAC. These safety and power-saving features make the VIPER113LS an excellent choice for creating robust and energy-efficient power supplies for consumer electronics, home appliances, and industrial equipment.

In summary, the VIPER113LS from STMicroelectronics is a versatile and reliable high-voltage converter that offers designers a powerful combination of performance, integration, and safety. Its robust design and comprehensive set of features make it an ideal choice for a wide range of power conversion applications.
