Power Supplies and Converters

There’re no secret when designing a power supply or a converter: regardless of the final use, they must provide high efficiency to meet requirements set by national and international initiatives including 80 PLUS®, ErP Lot 6 and Energy Star as well as power density, reliability and safety and all this at the appropriate price point.

To find the best solution for their applications, designers have to choose the most efficient power topology – fly-back, boost, or quasi-resonant – or the implementation – based on monolithic ICs or with discrete power switches and controllers – or even decide to use an advanced digital implementation. Whatever their choice, the right semiconductor products are key to meeting their specific design targets.

ST broad product portfolio includes highly-integrated AC-DC converters and controllers, monolithic DC-DC converters, silicon and silicon carbide (SiC) power MOSFETs and rectifiers, IGBTs and protection ICs, linear voltage regulators, battery management ICs - including wireless battery charger ICs – specifically designed digital controllers and STM32 microcontrollers. We also provide a comprehensive range of hardware and software evaluation and development tools including our eDesignSuite that helps engineers design high efficiency power supplies and converters.
