VIPER17L - High Voltage Converter from STMicroelectronics

The VIPER17L is a cutting-edge high voltage converter from STMicroelectronics, designed to deliver exceptional performance and reliability for a wide range of applications. This powerful component is part of the VIPerPlus family and integrates an 800 V avalanche-rugged power MOSFET with PWM current-mode control, making it an ideal solution for switched-mode power supplies.

With its robust design, the VIPER17L can withstand high energy bursts and offers increased power supply robustness through its integrated features. The device operates at a fixed 60 kHz switching frequency with a jittered version available to meet the requirements of low electromagnetic interference (EMI). It is specifically tailored for applications that demand high efficiency and compactness, such as adapters, power supplies for consumer electronics, and auxiliary power supplies.

The VIPER17L stands out with its built-in features that enhance both performance and safety. These include overvoltage protection, overload protection, thermal shutdown with hysteresis, soft-start, and a safe auto-restart after any fault condition removal. Its soft-start function reduces the stress on the components during the startup phase, thus increasing the reliability and lifespan of the power supply.

Furthermore, the VIPER17L's current-mode PWM controller offers excellent output voltage regulation and fast response to load transients. Its high voltage capability allows for direct connection to the rectified mains, eliminating the need for a power transformer and enabling the design of cost-effective power supplies with very low standby power consumption.

For designers looking to implement a high-performance power solution, the VIPER17L is available in several package options, including the DIP-7 and the smaller SO-16N. This flexibility allows designers to choose the best fit for their specific design constraints and manufacturing processes.

In summary, the VIPER17L from STMicroelectronics is a reliable and efficient choice for anyone in need of a high voltage converter that offers advanced protection features, high energy efficiency, and design flexibility, making it an essential component for modern power supply solutions.
