Description

STMicroelectronics VIPER100ASPTR-E: High-Voltage Converter

The VIPER100ASPTR-E from STMicroelectronics is a versatile, high-performance, and energy-efficient offline switched-mode power supply (SMPS) with a peak power capability. This integrated circuit is designed to deliver a stable and reliable power conversion solution for a wide range of applications, including adapters, chargers, and standby power supplies.

At the core of the VIPER100ASPTR-E is an advanced PWM controller with an 800 V avalanche-rugged power section, which enables the device to withstand high voltage surges and offers increased reliability. The high-voltage capability also simplifies the design by eliminating the need for an additional startup resistor, which is a common requirement in many other power supply designs.

The device incorporates a number of features that enhance its performance and ease of use. It includes a jittered switching frequency that reduces electromagnetic interference (EMI), making it suitable for applications where compliance with EMI standards is crucial. The VIPER100ASPTR-E also offers built-in protection features such as overvoltage protection, overload protection, thermal shutdown, and hysteresis restart that safeguard the IC and the power supply from various fault conditions.

With its low power consumption in standby mode, the VIPER100ASPTR-E meets the stringent requirements of energy-saving regulations, making it an eco-friendly choice for power supply designers. The device's power-saving capabilities are further enhanced by its ability to enter burst mode operation, which minimizes the power dissipation when the load demand is low.

For design flexibility, the VIPER100ASPTR-E supports both isolated and non-isolated topologies. It is available in a compact Pentawatt HV package, which not only saves space on the PCB but also simplifies the heat sinking process due to its excellent thermal characteristics.

In conclusion, the VIPER100ASPTR-E from STMicroelectronics is a highly integrated, robust, and energy-efficient solution for a variety of power supply applications. Its high-voltage capability, EMI reduction features, and comprehensive protection mechanisms make it a reliable and effective choice for designers looking to create compact, high-performance power supplies.
