In addition to their outstanding image quality, new-generation TVs gain attention for their slim silhouette, high-energy efficiency and low stand-by power. On all fronts, the power supply unit (PSU) plays a key role as it’s required to present a low-profile form factor.
To achieve these stringent requirements, today’s PSUs typically have a Power Factor Correction (PFC) stage and might use advanced topologies such as a half-bridge LLC (HB-LLC) resonant converter.
We have a broad portfolio of high-voltage MDmesh™ and low-voltage STripFET™ power MOSFETs, field-effect rectifier diodes (FERD), Schottky and Ultrafast diodes, a range of protection devices as well as dedicated analog and digital switching controllers and STM32 microcontrollers to enable developers to exploit the full potential of a digital PSU implementation.
