The VIPER35HD from STMicroelectronics is a state-of-the-art, high-voltage converter that integrates a PWM controller and a 730 V avalanche-rugged power MOSFET. This robust and efficient power solution is designed to deliver exceptional performance for a wide range of applications, including switched-mode power supplies (SMPS), LED drivers, and auxiliary power supplies in consumer, industrial, and computer domains.
One of the standout features of the VIPER35HD is its ability to operate over a wide input voltage range, which makes it particularly versatile for various electrical environments and conditions. Additionally, the device boasts an advanced jittered PWM controller, which not only enhances the power supply's efficiency but also minimizes electromagnetic interference (EMI), thus ensuring compliance with international EMI standards.
The VIPER35HD is engineered with several built-in protections to ensure the safety and longevity of the power supply and the end application. These protections include overload protection, overvoltage protection, hysteresis thermal shutdown, and a soft-start feature to prevent inrush current at startup. The device also features an error amplifier and an internal clamp which enables designers to easily implement feedback control loops for precise output regulation.
STMicroelectronics has also taken care of thermal management in the VIPER35HD, integrating a high-voltage startup circuit that minimizes standby power consumption. This feature, along with the device's low quiescent current, makes it an energy-efficient choice for applications that require compliance with energy-saving regulations.
For designers and engineers looking for a reliable and high-performance power conversion solution, the VIPER35HD presents an attractive option. Its compact size, combined with a minimal external component count, results in a reduced PCB footprint, making it ideal for space-constrained applications. With its robust design and energy-efficient operation, the VIPER35HD is poised to be a key component in the next generation of power supply designs.
