'Industry's first' PMICs for smart TVs & set-top boxes

Jalal Bagherli, CEO, Dialog Semiconductor, commented: "Dialog invented the high integrated configurable PMIC concept for smartphones, tablets and other portable devices and we lead the market today. We have now adapted the concept to the power architecture of TVs and the resulting PMICs will radically change for the better how the TV analogue power path will be designed going forward. There has been an absence of analogue innovation in TVs for years, something that we're changing with this new generation of products. The technology is based on our heritage of mobile market success and we will once again deliver compelling benefits to consumer product manufacturers."

According to analyst Gartner, over 550m TVs and STBs will be made in 2017. Increasing demand for 4K televisions is driving TV sales growth and the STB market is experiencing particularly rapid expansion in India and China. In addition, the advent of media streaming services such as Netflix, Hulu and Amazon TV has created new products such as video streaming sticks and personal media boxes in which the new PMICs may also be used.

Cost savings will be achieved because one PMIC will replace up to 130 discrete components typically found in a TV today. As a result, PCBs can be simpler and less expensive. Pick-and-place assembly will be up to three times faster, cutting manufacturing costs, and by standardising the analogue power path with a few programmable power management devices across a wide range of applications, manufacturers will reduce both R&D and inventory costs.

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. Using Dialog PMICs guarantees system cost reduction, improved power efficiency, enhanced performance and greater reliability.

Compared with power management designs that use discrete components, greater efficiency will deliver energy savings of up to 5W. Less heat needs to be dissipated, resulting in increased reliability, which is further enhanced because there are fewer components and connections. Designs will be simplified because the PMICs enable centralised control of the whole TV or STB power path. In addition the regulatory requirements around the world are pushing for lower standby power dissipation, typically below 300mW, which can be readily met using a PMIC-based system design.

Samples of Dialog's TV PMICs are available now and the company will be ramping to high volume production in the second half of this year.
