With robust, advanced high-voltage converters, power factor correctors, a variety of controllers and supervisors/housekeeping ICs, together with innovative architectures and extended temperature ranges.
ST can offer integrated solutions and meet all switching-mode power supply design needs.
New generation AC-DC converters reduce power consumption and increase efficiency, essential for powering the majority of mains equipment. When combined together, ST power factor correctors, PWM controllers and offline converters significantly lower system power consumption to outperform the most demanding energy-saving regulations, such as 80 PLUS® Initiative, ErP Lot 6, Energy Star, and many others.
