VIPER15LD Application Field and Working Principle

The VIPER15LD is an integrated circuit designed for use in AC-DC converters and offline switchers. It is manufactured by the international semiconductor and embedded systems company, STMicroelectronics. The chip is part of the VIPER portfolio and is designed for applications including electric motor controllers, telecommunication power supplies, server power supplies, point of load converters, lighting ballasts, and general low power motor control systems.

The VIPER15LD is a monolithic integrated circuit with an integrated power switch and inrush current limiter. It is a complete implementation of the current doubler PFC transformerless power supply with the complete rectifier and controller built into a single chip. This helps to reduce the number of external components that are required and therefore reduce overall system costs.

At the heart of the VIPER15LD is the J-FET input current doubling boost regulator. The chip has an integrated secondary rectifier and two independent output control channels that together create an innovative solution for powering AC/DC converters and offline switchers. The dual output control channels also offer an adjustable phase shift between the outputs to further reduce losses, which allows the chip to operate efficiently even at very low input voltages.

The VIPER15LD also features a wide range of protection including thermal shutdown, over voltage protection, under voltage lock-out, overtemperature protection, and open-loop protection. Additionally, it is designed to minimize the amount of electromagnetic interference (EMI) and is suitable for the most stringent EMI standards.

In summary, the VIPER15LD is an advanced, efficient, and reliable integrated circuit for powering AC/DC converters and offline switchers. With its current doubler PFC transformerless power supply and its integrated secondary rectifier, it offers a complete solution for low power motor control applications in a single chip. It also features a wide range of protective features and is designed to minimize the amount of EMI.
