STMicroelectronics Helps Manufacturers Target Mainstream Market Opportunities by Simplifying Blu-ray Design

The new STODD01 is a power-supply IC capable of generating all the voltages needed to operate the player’s circuitry, including the high-voltage driver for the blue laser supporting HD read/write capabilities. The device integrates three power supplies to drive low-voltage digital ICs, analog circuitry, and the laser driver. Using this chip, designers can eliminate multiple individual power supplies from the printed-circuit board, reducing component costs, design complexity, time to market, and assembly time. The size of the board can also be reduced, which will allow new generations of compact set-top products, game consoles, PC drives and portable HD devices.

Each of the STODD01’s power-supply channels benefits from highly efficient switched-mode conversion, which minimizes energy losses and heat generation. The device also provides a true shutdown mode, helping to minimize standby power consumption. This enables HD products to attract buyers by offering enhanced user experiences and low operating costs. A major manufacturer of DVD and Blu-ray equipment has already qualified the STODD01, recognizing the importance of superior power management as the markets for HD equipment evolve.

Major features of STODD01:

* Three power-supply channels for: HD digital ICs; DSPs and RF amplifier; and blue laser driver
* 0.8A buck converter for digital circuitry
* Programmable laser-driver output voltage allows use in battery-powered equipment
* Reset control
* QFN16L 4 x 4mm package
