STMicroelectronics VIPER012LSTR: High-Voltage Converter

The VIPER012LSTR from STMicroelectronics is a cutting-edge, high-voltage converter that offers an efficient and compact solution for power supply applications. This device is part of the VIPerPlus family and integrates a PWM controller and a 730V avalanche-rugged power MOSFET. It is designed to meet the stringent requirements of both industrial and consumer electronics by providing a highly reliable power conversion mechanism.

One of the standout features of the VIPER012LSTR is its energy-saving capabilities. It employs advanced energy-saving features such as the proprietary Energy Saving mode, which allows it to achieve less than 30mW (at 265VAC) of no-load power consumption. This makes it an excellent choice for applications that require compliance with energy-efficient standards.

The device is versatile and can be used in a wide range of offline power supply applications, including adapters, chargers, and auxiliary power supplies. Its integrated features such as soft-start, error amplifier, and oscillator with jitter allow for a simplified circuit design, reducing the number of external components needed and ultimately minimizing the overall solution size.

Additional protection features ensure the VIPER012LSTR operates safely under various conditions. Overvoltage protection (OVP), overload protection (OLP), thermal shutdown (TSD), and hysteretic overcurrent protection (OCP) are all built-in, safeguarding the device and the system it powers from potential damage caused by abnormal operating conditions.

The VIPER012LSTR is available in an SSOP10 package, offering a compact footprint for space-constrained applications. Its high level of integration and robustness make it a preferred choice for designers looking to create reliable and high-performance power supplies with minimal external components and reduced development time.

In summary, the VIPER012LSTR is a highly efficient, versatile, and robust high-voltage converter from STMicroelectronics, designed to meet the needs of modern power supply designs. It is a testament to STMicroelectronics' commitment to delivering innovative and energy-efficient power solutions to the market.
