Key Products
Beyond their outstanding image quality, new-generation televisions have a very thin design, are highly power-efficient and feature a stand-by power mode. Power Supply Units (PSUs) play a key role in ensuring TVs meet market requirements and have an elegant form factor. To achieve these stringent requirements, today's PSUs feature a Power Factor Corrector (PFC) and often use advanced topologies such as half-bridge LLC (HB-LLC) resonant converters.

Our products and solutions

In order to help design engineers implement a digital PSU, ST offers a broad portfolio of high-voltage MDmesh™ and low-voltage STripFET™ power MOSFETs, Field-Effect Rectifier Diodes (FERD), Schottky and ultra-fast diodes, protection devices, dedicated analog and digital switching controllers as well as STM32 microcontrollers.
