The VIPER013XSTR application field and working principle have been made possible by the introduction of Power Management Integrated Circuits (PMIC) and power electronics such as AC/DC converters, offline switchers, and motor drivers. The VIPER013XSTR is a polyphase low-voltage integrated circuit specifically designed for universal AC/DC and offline switcher applications. It is essentially a polyphase power factor correction (PFC) offline power factor correction (PFC) converter with integrated polyphase MOSFETs and dedicated gate-drive circuits.

The VIPER013XSTR integrates 6-phase MOSFETs to form a single monolithic device with 3 high-side and 3 low-side MOSFETs. Each MOSFET has its own dedicated gate drive circuit, and comes with overcurrent, overvoltage, and over-temperature protections. The VIPER013XSTR can switch up to a maximum of 400V at a frequency of up to 1MHz. It supports a wide range of operating conditions, including asymmetric and symmetric operating modes, and can operate from 38V to 400V.

The VIPER013XSTR provides many advantages in terms of power application field and working principle, including high efficiency, reduced system cost, and improved EMI performance. It can be used for high power AC/DC applications, such as power adapters and power supplies, as well as high power offline switchers, such as SMPS or quasipower-factor-corrected systems. Its built-in multi-phase control and protection features make it an ideal choice for universal AC/DC and offline switcher applications that require high reliability and accuracy, such as white goods, telecommunications, and electric vehicle chargers.

The VIPER013XSTR\'s innovative PFC design helps to reduce register-to-register and class variation in the output waveform. This ensures an accurate output voltage and power rating, as well as improved efficiency, even with variable input voltage and current. Additionally, the VIPER013XSTR incorporates a selectable demagnetization control logic with two independent voltage sense pins and two independent current sense pins. This helps to minimize the output voltage and current levels around the nominal value of the system.

The VIPER013XSTR also provides integrated over-temperature protection and an adjustable under-voltage lockout (UVLO) feature for added reliability. This ensures the highest safety level in the system and prevents failure due to over-temperature or over-current conditions. Additionally, the device supports a wide range of input voltages and currents and can be used in a variety of AC/DC and PFC applications such as healthcare, military/aerospace, automotive/industrial, computing, and consumer electronics.

In conclusion, the VIPER013XSTR is a powerful and reliable power management integrated circuit specifically designed for AC/DC and offline switcher applications. Its features, such as a wide operating range, multi-phase control, integrated over-temperature protection, and adjustable undervoltage lockout, make it an ideal choice for high power AC/DC and PFC applications. Its innovative PFC design also helps to reduce register-to-register and class variation in the output waveform, ensuring an accurate output voltage and power rating, as well as improved efficiency, even with variable input voltage and current.
