VIPER01, suitable for smart home and industrial applications

STMicroelectronics (hereinafter ST) has released a new high-voltage power converter, the VIPER01. With a 5V output voltage, it enables the design of a simple and cost-effective Switched-Mode Power Supply (SMPS) with ultra-low power consumption.

VIPPER01 is ideally designed for small industrial/consumer applications as well as low-power applications such as home appliances, buildings, lighting, and motion control. It can operate directly from the main rectifier power supply and integrates an excellent 800V avalanche-rugged power MOSFET, Pulse-Width Modulation (PWM) current-mode control, and multiple protection circuits, making it suitable for providing auxiliary power to microcontrollers in IoT devices that are continuously connected to the Internet or local networks.

VIPER01, part of the VIPerPlus™ high-voltage converter family, is a second-generation product featuring ST's unrivaled BCD (Bipolar-CMOS-DMOS) technology. BCD technology integrates a high-performance PWM controller, high-voltage logic-level control transistors, and protection and diagnostic circuits onto a single chip without significantly impacting the robustness and reliability of the power transistors.

VIPER01 is a product capable of meeting the strictest standard requirements for energy saving because it has very low power consumption and can automatically switch to pulse frequency modulation under low load conditions. It can be used in fly-back, buck, and buck-boost converter topologies and includes an oscillator with integrated high-voltage start-up, sense-FET, error amplifier, and jitter, allowing for the design of complete applications while minimizing the number of external components.

VIPER01 comes with a series of tools, including an evaluation kit, application notes, and a spice model capable of jump-starting a more robust, safe, and cost-effective SMPS design.
