The STMicroelectronics VIPER28LD is a high-voltage converter IC that integrates an 800V power MOSFET with PWM current-mode control. It is designed for flyback topology applications and operates with a switching frequency of 60kHz. This device is suitable for auxiliary power supplies in consumer and home equipment, energy meters, and data concentrators.
Key electrical specifications include a wide input voltage range of 8.5V to 23.5V, an 80% duty cycle, and a breakdown voltage of 800V. The IC offers various fault protection features such as current limiting, over-temperature, over-voltage, and short circuit protection. It operates within a temperature range of -40°C to 150°C (TJ).
The VIPER28LD is available in a 16-SOIC surface mount package. Its design incorporates features like embedded HV startup and sense FET, jittered frequency for reduced EMI, and automatic restart after a fault condition, contributing to system reliability and extended IC lifetime. The device also meets RoHS3 compliance standards.
