The VIPER011XSTR is a latest-generation PWM controller with an integrated voltage regulator, designed for exceptional performance and flexibility. It features an integrated logic level boost circuit and voltage regulator to support a wide range of AC and DC loading conditions. The VIPER011XSTR combines features of the VIPER011DX and VIPER012CR to provide a more complete power management solution for AC-DC and DC-DC conversion. It offers high efficiency, low EMI and fast start-up.
In AC-DC applications, the VIPER011XSTR allows a designer to optimize the efficiency of the system and select the best topology for a given application. The device can be used as either a synchronous or asynchronous buck converter. When operating as a synchronous buck converter, the VIPER011XSTR provides an integrated inductor current detector and phase-lock loop (PLL) to reduce EMI without the need for external components. It also incorporates an under-voltage lockout (UVLO) feature to protect the device and its load against voltages below the rated range.
The VIPER011XSTR can also be used in isolated DC-DC applications for standard or alternative topologies. It provides adjustable output voltage transient response with fast transient jitter-free response and line feed-forward compensation over temperature from -40 °C to 90 °C. Various fault detections including over-current and over-voltage are also provided, making the device ideal for industrial, communication and computer application.
In addition, the VIPER011XSTR contains built-in features for EMI mitigation, such as spread spectrum and disabling of the pulse-by pulse current limit when the input supply voltage is changing. These features help reduce conducted and radiated EMI on AC line-connected sources, improving system performance while simplifying external components.
The VIPER011XSTR includes a built-in voltage regulator, allowing the designer to configure the output voltage required for the application. The voltage regulator can also be set to operate in both buck and boost configurations. This reduces the development time and cost for the designer as it eliminates the need to design and include an external constant voltage regulator.
In short, the VIPER011XSTR is a highly flexible and efficient AC-DC and DC-DC converter with an integrated voltage regulator. Its integrated logic level boost and voltage regulator allow it to operate in both buck and boost configurations. Its various protections and noise reduction features make it well suited for a wide range of industrial, communication and computer applications.
