AC-DC power supply units used in servers and telecom infrastructures are required to provide an increased level of efficiency and improved power factor to meet requirements such as the gold, platinum or titanium levels of the 80 PLUS voluntary certification program in addition to enhanced reliability for continuous operation or use in redundant systems. To meet these challenging performance targets, architectures implementing advanced control algorithms are built with high-performance digital controllers.

To help design high-efficiency power supply units (PSU) with high power density, ST offers a range of power MOSFET and rectifiers – including those based on silicon carbide (SiC) – and advanced analog and digital controllers. In addition, developers will benefit from our high-performance STM32 microcontrollers – with an extended range of dedicated peripherals including high-resolution PWM timers and high-speed ADCs – together with our hardware and software evaluation and development tools including reference designs.
