Brief Description of VIPER22A

The VIPER22A is a high-voltage, low-power, off-line converter integrated circuit (IC) designed for low-power switch mode power supply (SMPS) applications. It is commonly used in various power supply and adapter applications to convert high-voltage AC power to low-voltage DC power efficiently. Here are some key features and specifications of the VIPER22A SMPS controller IC:

Input Voltage Range: The VIPER22A is designed to work with a wide range of input voltages, typically from 85V AC to 265V AC, which includes standard mains voltages.

Switching Frequency: It typically operates at a fixed switching frequency, often in the range of 50 kHz to 100 kHz, depending on the specific model and application requirements.

Integrated MOSFET: The VIPER22A features an integrated power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) that is used to control the output voltage efficiently.

Low Standby Power Consumption: The VIPER22A is known for its low standby power consumption, which is important for energy-efficient power supply designs.

Overvoltage and Overcurrent Protection: It includes built-in protection features, such as overvoltage and overcurrent protection, to enhance safety and reliability.

Pulse Frequency Modulation (PFM): The VIPER22A may support pulse frequency modulation for improved light-load efficiency.

Package: The VIPER22A is typically available in a small surface-mount SMD package, making it suitable for compact and cost-effective power supply designs.

Applications: The VIPER22A is commonly used in low-power switch mode power supplies, AC/DC converters, battery chargers, LED drivers, and other power management applications.

Feedback Control: The VIPER22A provides feedback control for regulating the output voltage, which can be adjusted as needed for the specific application.

Protections: In addition to overvoltage and overcurrent protection, the VIPER22A may include features like thermal shutdown and short-circuit protection.
