Mouser Now Stocking the Ultra-Low-Power-Consumption VIPer01 High-Voltage Converters from STMicroelectronics


Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the VIPer01 high-voltage converters from STMicroelectronics (ST). Part of the VIPerPlus family of high-voltage converters based on ST’s Bipolar-CMOS-DMOS (BCD) technology, the VIPer01 devices are offline, high-voltage AC/DC converters that integrate an 800V avalanche-rugged MOSFET with pulse-width modulation (PWM) current-mode control and multiple protection circuits.


Supporting flyback, buck, and buck-boost topologies, the converters feature an integrated high-voltage start-up and sense-FET, error amplifier and oscillator with jitter — all helping to minimize the number of external components required to design a complete application. With its robust feature set and ultra-low-power-consumption designed to meet stringent energy standards, the VIPer01 converters enable engineers to build simple and cost-effective switched-mode power supplies (SMPS) with a 5V output for use in home appliances, building control, lighting, motion control, and small industrial and consumer applications.


ST’s VIPer01 high-voltage converters, available from Mouser Electronics, operate directly from a rectified mains supply and incorporate an 800V avalanche-rugged power MOSFET that allows for an ultra-wide VAC input range. The devices offer low power consumption and switch automatically to pulse frequency modulation (PFM) under light load conditions. On-board protection circuitry consists of drain-current limit, overload, short circuit, overvoltage and embedded thermal shutdown. Additionally, the devices include a built-in soft-start to improve system reliability, and offer a tailored auxiliary supply to microcontrollers in Internet of Things (IoT) applications that are permanently connected to the Internet or a local network.


Due to the converters’ low power consumption and automatic PFM operation under light load conditions, the VIPer01 meets many stringent energy-saving standards, including U.S. Energy Star and the European EuP Lot 6 Tier 2 of the EC Ecodesign Directive. System input power consumption is less than 10 mW at 230 VAC in a no-load condition, and less than 400 mW at 230 VAC with a 250-mW load.


ST’s VIPer01 high-voltage converters are available in a 10-lead SSOP package, and are supported by two evaluation boards: The STEVAL-ISA177V1 is based on a non-isolated flyback converter and is jittered at 120 kHz, whereas the STEVAL-ISA178V is based on a non-isolated buck converter and is jittered at 30 kHz.
