VIPER37LE

The VIPER37LE is a component that belongs to the PMIC category, specifically to the categories of AC DC converters and offline switchers. It is an integrated component package that can perform AC/DC conversion and switching between two power supplies, enabling higher efficiency and improved power management. To understand how it works, one needs to know its application field and working principle.

Application Field

The VIPER37LE is primarily used in telecom, industrial, and high-end computing applications. It is the ideal component for applications that require hundreds of watts of power without extra board space. Its multiple high-voltage rated switches enable efficient power conversion, while its IO capabilities allow for faster communication between power sources and loads. Additionally, the component provides protection against over-current, over-voltage, and thermal overloads.

Working Principle

The VIPER37LE is a two-stage device that uses two sets of switches to control the AC/DC conversion process. During the first stage, the device’s MOSFETs switch back and forth, while the second stage uses a synchronous rectification technique to achieve higher efficiency. This technique reduces switching losses and also increases the speed at which the conversion happens. The VIPER37LE also has an internal power factor correction circuit that can optimize the power input equal to or greater than 0.95.

The device has the capability to control and monitor the entire system by utilizing a communication interface, such as CAN, SPI, and I2C. Additionally, it is equipped with three independent error detection systems - an over-voltage, an under-voltage, and a current-limit circuit. These circuits allow for reliable and accurate power management and ensure power supply safety from possible faults.

The VIPER37LE is a versatile and efficient component for AC/DC switching and power management. Its application field covers telecom, industrial, and high-end computing applications that need higher efficiency and improved power management. It is also equipped with multiple protection circuits, making it reliable and safe to use.
