The VIPER06XSTR is a high-performance offline converter from STMicroelectronics that integrates a PWM controller and a 700 V vertical power MOSFET in one package. This energy-efficient component is designed for switched-mode power supplies and is particularly suited for applications requiring a low power consumption in standby mode, such as home appliances, auxiliary power supplies, and power adapters.

Key Features

• High-Voltage Capability: With an integrated 700 V rugged power section, the VIPER06XSTR is capable of sustaining high voltage levels, making it ideal for a wide range of input voltages.
• Energy Efficiency: The device boasts a very low quiescent consumption under no-load conditions, and an excellent efficiency at light loads, thanks to its advanced burst-mode operation.
• Enhanced Power Management: It includes a jittered switching frequency reducing EMI filter cost, and features such as soft-start, burst-mode operation, and under-voltage lockout with hysteresis.
• Protection Features: The VIPER06XSTR ensures safe operation with its built-in protections against overvoltage, overload, short-circuit, and thermal shutdown with automatic restart.
• Compact Design: Its SO-16N narrow form factor enables the design of compact power supplies, reducing the overall bill of materials and simplifying the PCB layout.

Applications

The VIPER06XSTR is versatile and can be used in a variety of applications, including:

• SMPS for home appliances and smart meters
• Auxiliary power supplies for white goods and industrial systems
• Standby and auxiliary power supplies in TVs and monitors
• AC/DC adapters for low power equipment

Technical Specifications

Some of the technical specifications of the VIPER06XSTR include an extended VDD voltage range (4.5 V to 30 V), a current capability of 30 mA, and a fixed 60 kHz switching frequency with frequency jittering for lower EMI.

For engineers and designers who require a reliable and efficient power conversion solution, the VIPER06XSTR offers a balance of performance, protection, and ease of design, making it a go-to choice for a wide array of low-power applications.
