STMicroelectronics VIPER15LN - High-Voltage Converter

The VIPER15LN from STMicroelectronics is a robust and efficient offline high-voltage converter that is part of the VIPerPlus family. This powerful device integrates an 800 V avalanche-rugged MOSFET with PWM (Pulse Width Modulation) current-mode control, making it an excellent choice for a wide range of power supply applications. The VIPER15LN is designed to deliver a compact and cost-effective solution for power supplies, offering a minimal component count and enhanced reliability.

One of the standout features of the VIPER15LN is its ability to operate over a wide input voltage range, which ensures flexibility in various application scenarios. The device is capable of providing a constant output power with an extended range of input voltages, which is particularly useful for fluctuating mains supplies. Additionally, the VIPER15LN boasts advanced protection features, including overload protection, overvoltage protection, and thermal shutdown with hysteresis, which safeguard the device and the system it powers against a variety of fault conditions.

The energy-efficient nature of the VIPER15LN is highlighted by its low power consumption under standby conditions, which makes it suitable for designs that require compliance with energy-saving standards. Furthermore, the built-in soft-start function reduces the stress on the system during the startup phase, thereby enhancing the longevity of the product.

Another advantage of the VIPER15LN is its integrated frequency jittering, which significantly reduces the electromagnetic interference (EMI) generated by the converter. This feature simplifies the design of EMI filters and helps in meeting regulatory standards for electromagnetic compatibility (EMC).

Designed with practicality in mind, the VIPER15LN is available in a compact DIP-7 or SO-16N package, which is ideal for applications with limited PCB space. Whether it's for power adapters, auxiliary supplies, or other AC/DC converter applications, the VIPER15LN is a versatile and reliable choice that engineers can depend on for efficient power conversion.

Overall, the VIPER15LN is a testament to STMicroelectronics' commitment to providing innovative power solutions that combine performance, efficiency, and reliability for a diverse array of electronic applications.
