AC DC Converters, Offline Switches

VIPER16HD Description

The VIPER16HD from STMicroelectronics is a high-performance offline switcher IC designed for robust AC/DC power conversion applications. Part of the VIPer™ plus series, it integrates an 800V avalanche-rugged power MOSFET, enabling reliable operation in demanding environments. With a switching frequency of 115kHz, it supports up to 10W power output and features a wide supply voltage range (11.5V–23.5V), making it versatile for various designs. The device includes built-in fault protection (current limiting, over-temperature) and offers either isolated or non-isolated output configurations, providing flexibility in system integration. Its 13V startup voltage ensures stable initialization, while the 70% duty cycle optimizes efficiency.

VIPER16HD Features

• Integrated 800V Power MOSFET: Enhances durability and reduces external component count.
• Multi-Topology Support: Compatible with flyback, buck, and buck-boost configurations.
• Comprehensive Protection: Current limiting and thermal shutdown for enhanced reliability.
• Wide Vcc Range (11.5V–23.5V): Suitable for universal input voltage applications.
• Low Startup Voltage (13V): Ensures quick and stable power-up.
• RoHS3 & REACH Compliant: Meets stringent environmental and safety standards.
• Surface-Mount 16SO Package: Compact and suitable for automated assembly.

VIPER16HD Applications

The VIPER16HD excels in low-power SMPS designs, including:

• Auxiliary Power Supplies: For industrial control systems and appliances.
• LED Drivers: Efficient power management for lighting solutions.
• Consumer Electronics: Adapters, chargers, and set-top boxes.
• IoT Devices: Compact, energy-efficient power conversion for smart sensors.
  Its either isolated or non-isolated output flexibility makes it ideal for designs requiring safety isolation (e.g., medical or industrial) or cost-sensitive non-isolated solutions.

Conclusion of VIPER16HD

The VIPER16HD combines high integration, robust protection, and multi-topology support, making it a standout choice for 10W offline power supplies. Its 800V MOSFET, wide input range, and fault protection ensure reliability in harsh conditions, while the surface-mount package simplifies manufacturing. Whether for consumer electronics, industrial systems, or LED drivers, the VIPER16HD delivers efficiency, compactness, and compliance with global standards.
