VIPER100A-E Application Field and Working Principle

PMIC - AC DC Converters, Offline Switchers

The VIPER100A-E is an integrated Offline Switcher controller solution specifically designed to meet the energy-savings requirements of off-line AC/DC power supplies. It consists of an integrated gate driver and controller IC, optimized to reduce power losses in the power supply system. The VIPER100A-E is marketed as a universal solution for both low-end and high-end applications and its integrated burst-mode or fixed-frequency controller eliminate the need for a separate driver or micro-controller. The VIPER100A-E is perfect for low-cost, low-power circuits that don\'t require a full-fledged micro-controller, but still require a highly efficient AC/DC converters. Its integrated modulation circuitry makes it perfect for applications where board size is important without sacrificing performance. The VIPER100A-E supports a wide range of output ratings, making it suitable for a variety of applications. The VIPER100A-E utilizes an integrated quasi-resonant topology which allows the device to work in either burst mode or fixed frequency with the same components. This allows the device to maintain high power efficiency by running at a lower switching frequency when the system is not demanding too much. By lowering the switching frequency, the device reduces both the size and the loss in low demand systems. The VIPER100A-E also features integrated soft-start, timeout and short circuit protection to ensures safe start-up and shutdown of your power supply. It also has adjustable current and voltage protection thresholds which can be set to safety limits, ensuring system stability. Finally, the VIPER100A-E provides high precision voltage feedback and enable pins to allow for precise current and voltage control. Its integrated 4-channel opto-coupler provides up to 4 isolated feedback signals, allowing for paralleling multiple chips for higher power outputs. Overall, the VIPER100A-E is a highly efficient and cost-effective solution for a variety of off-line AC/DC power conversion applications. It is designed to reduce operating power losses and increase power efficiency, while enabling a compact and low-cost design. The device, with its integrated controllers and driver, eliminates the need for a dedicated micro-controller and provides precise current and voltage control with low power consumption. The VIPER100A-E is the perfect choice for a wide range of low-end and high-end applications. The device\'s highly efficient quasi-resonant topology reduces the operating losses and allows for an efficient switch-mode power supply, while the integrated modulation and soft-start circuitry ensures fast start-up, safety and reliability. In addition, the device provides precise current and voltage control with integrated opto-couplers as well as adjustable current and voltage protection thresholds. The VIPER100A-E may be the perfect solution for many off-line AC/DC power conversion applications.
