Stock Supply Of ST VIPER318HDTR — High-Efficiency Energy-Saving Offline High-Voltage Converter

Mingjiada Electronics supplies STMicroelectronics VIPER318HDTR high-voltage converter product introduction:

STMicroelectronics VIPER318HDTR is a highly integrated, low-power offline high-voltage converter suitable for applications such as home appliances, industrial control, smart home, and low-power adapters. The chip is packaged in a 16-SOIC package, integrates an 800V avalanche-hardened power MOSFET, and supports multiple topology structures (flyback, buck, boost, etc.), significantly simplifying power design and reducing BOM costs.

The VIPER318HDTR belongs to ST's VIPerPlus series, an energy-efficient offline high-voltage converter with an integrated dithering PWM controller (supporting adjustable frequencies of 30kHz/60kHz/132kHz) and a high-voltage startup circuit, suitable for non-isolated power supply designs. Its key features include:

800V-rated power MOSFET for enhanced system reliability.

Ultra-low standby power consumption (20mW @265V AC input), compliant with global energy efficiency standards.

Wide input voltage range (supports 24V DC startup), suitable for global power grids.

Integrated multiple protection functions (overvoltage, overcurrent, short circuit, over-temperature), enhancing system stability.

Technical specifications:

Operating voltage range: 4.5V to 30V

Startup voltage: 8V

Switching frequency: 132kHz

Power: 1W

Operating temperature: -40°C to 150°C (TJ)

Package: 16-SOIC (0.154, 3.90mm width)

Functional Features:

Supports multiple topologies: supports boost, buck, buck-boost, flyback, and other topologies.

Multiple protection functions: Features overload, overpower, over-temperature, overvoltage, and short-circuit protection functions to ensure safe operation under abnormal conditions.

Soft-start function: Includes soft-start control characteristics to effectively reduce inrush current during startup and extend device lifespan.

VIPER318HDTR Typical Applications

Home appliance power supplies: Air conditioner control boards, washing machine power modules.
