High-voltage power converter

STMicroelectronics has introduced a high-voltage power converter that allows designers to build a low-consumption, cost-effective Switched-Mode Power Supply (SMPS) with a 5V output voltage.

The VIPER01 is suited for low-power applications in home appliances, building, lighting and motion control, as well as industrial and consumer applications. It operates directly from a rectified mains supply and integrates an 800V avalanche-rugged Power MOSFET with Pulse-Width Modulation (PWM) current-mode control and multiple protection circuits. Furthermore, it is tailored to provide the auxiliary supply to microcontrollers in IoT devices that are permanently connected to the Internet or a local network.

According to the company, the converter enables designers to meet stringent energy-saving standards due to its low power consumption and its ability to switch automatically to pulse frequency modulation under light load conditions. It can be used in fly-back, buck-boost converter topologies, while the integrated high-voltage start-up, sense-FET, error amplifier, and oscillator with jitter allow a complete application to be designed with the minimum number of external components.
