Introducing the VIPER265KDTR from STMicroelectronics

The VIPER265KDTR is a cutting-edge, high-performance offline switched-mode power supply (SMPS) controller designed by STMicroelectronics, a global leader in semiconductor solutions. This advanced component is part of the VIPerPlus series, which is renowned for its energy efficiency and reliability in power conversion applications.

At the heart of the VIPER265KDTR is a rugged 800 V avalanche-rugged power section, a PWM operation at 60 kHz with a frequency jittering feature for lower EMI, and multiple protection features that ensure robustness and enhanced safety. This innovative controller is optimized for SMPS designs, enabling compact, energy-efficient power supplies for a wide range of applications, including consumer electronics, home appliances, office equipment, and industrial systems.

The device integrates a high-voltage startup circuit that allows the quick and efficient startup of the power supply, minimizing standby power consumption. Its built-in error amplifier, along with an accurate (±1%) internal reference voltage, ensures precise output voltage regulation. The VIPER265KDTR also features an adjustable overcurrent protection, which safeguards the system against short circuits and overloads.

One of the key advantages of the VIPER265KDTR is its flexibility. It supports both isolated and non-isolated topologies, such as flyback, buck, and buck-boost converters, making it a versatile choice for designers. Additionally, the controller's integrated soft-start function ensures a smooth and gradual increase in the output voltage, which helps to prevent stress on the power supply components during startup.

Thermal shutdown with automatic restart ensures the VIPER265KDTR operates within safe temperature limits, thereby protecting both the power supply and the end application from thermal-related issues. The device also comes in an eco-friendly package, minimizing the environmental impact and meeting the latest international regulations for electronic products.

In summary, the VIPER265KDTR from STMicroelectronics is a highly reliable and efficient solution for modern power supply designs, offering a combination of performance, safety features, and design flexibility that make it an excellent choice for a wide range of electronic applications.
