TowerJazz and OnSemi Collaborate on Programmable PMIC for LCD and AMOLED Panels
TowerJazz has joined forces with ON Semiconductor to deliver an advanced programmable power management IC (PMIC) and high voltage level shifter with VCom targeting the high-end display panel market. This unique part is capable of driving very large loads with different voltage ranges and features a programmable power sequence that allows the product to be applied to various applications. To accommodate display panel market requirements, the part was designed to drive both positive and negative voltages (42V differential) to support essential high-voltage product specifications. It is also applicable for the various panel applications in customer markets such as monitors and televisions, both small and large displays.
The collaboration leverages TowerJazz's latest TS35 power management platform for design and manufacturing to create a market leading product which is ramping to volume production. The device will be used for applications such as different sizes of LCD and AMOLED panels. According to a global TV shipment report by NPD DisplaySearch, the overall TV market in 2012 was forecast at 245 million units and several key high value segments of the TV business such as large screen sizes and LED-backlit LCD TVs are expected to continue to grow.
TowerJazz's collaborative efforts created the most cost-effective advanced product making use of the unique features in its TS35PM platform. This process offers a low mask count with the ability to generate one boost up and two step down voltage and two high voltage reference (in this case, negative voltages as well as positive voltages to meet market required performance), and fully scalable HV transistors for area optimization.

Along with these features, TowerJazz utilized its world class process design kit (PDK) and design services. TowerJazz's sophisticated PDK which includes scalable devices enabled the team to quickly design and simulate the product ensuring it met the required performance and target die cost. In addition, the high voltage span requirement is designed with a minimum mask count, further reducing the product's cost.
"The long-standing partnership between TowerJazz and ON Semiconductor has produced many successful products for various markets. This unique relationship combines ON Semiconductor's market position and understanding of the system with our intimate knowledge of our power management platform," said Ori Galzur, Vice President of TowerJazz Design Center and Design Enablement. "TowerJazz's design and manufacturing knowledge accelerates development time, allowing faster production ramp. This enables our customers to focus on their system knowledge while we assist by providing design services and save them the learning curve."
Opinion: Maximising Synergies between Power Electronics and ICT for improving Energy Efficiency
"TowerJazz's advanced technology enables ON Semiconductor to define and develop new products increasing our market share with existing and new customers," said Simon Keeton, Vice President and General Manager of ON Semiconductor's Consumer Products Division. "For the advanced display panel market, TowerJazz's power management platform was the natural choice because it enables us to produce the most cost-effective products from die size and mask count aspects while leveraging integration strategies to include Vcom, Gamma, and PMIC/HVLS to meet various customer needs. There is also a benefit derived from designing, manufacturing and the fast production ramp that can be achieved with a single foundry partner."

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.
