Dialog Semiconductor has configured a device as its entry to the smart TV and set-top box (STB) market, with a family of highly integrated PMICs (power-management ICs); three PMICs span low to high-end smart TVs. The devices were developed in partnership with TV System-on-Chip (SoC) vendors and have been demonstrated in several reference designs.

Dialog claims leadership in high integration configurable PMICs for smartphones, tablets and other portable devices; the company says it has adapted the concept to the power architecture of TVs and the resulting PMICs will “radically change” how the TV analogue power path will be designed going forward. There has, a spokesman asserts, been an absence of analogue innovation in TVs for years… “the technology is based [Dialog’s] mobile market success and we will once again deliver compelling benefits to consumer product manufacturers.”

Costs savings will be achieved because one PMIC will replace up to 130 discrete components typically found in a TV today. As a result, printed circuit boards can be simpler and less expensive.

The power requirements of SoC devices in TVs and STBs are becoming more complex as video processing technology advances. The processors require precise, highly efficient power supplies with dynamic voltage scaling and low ripple and noise, the latter to ensure improved picture stability. Dialog promises system cost reduction, improved power efficiency, enhanced performance and greater reliability with its PMICs. Greater efficiency will deliver energy savings of up to 5W. Regulatory requirements around the world are pushing for lower standby power dissipation, typically below 300 mW, which can be readily met using a PMIC-based system design.
