Mr David Kwong
ASTRI AMS group will propose specifications and complete the design, simulation, layout and evaluation of silicon IP blocks to be used in the Pico Projector systems. The IP blocks include programmable LED drivers and programmable DC/DC converters. The interface circuitry to the projector system will also be developed in order to achieve an integrated solution. Below is a summary of the deliverables: a. LED drivers with programmable range from 200mA to 800mA b. DC/DC converters accepting 2.5V to 5V battery input, producing regulated output voltages from 1.2V to 5V c. Integrated IC containing the LED driver, DC/DC converters and a 100MHZ serial communication port, fabricated with 0.25/0.35um 5/12V HV process

The ever smaller personal electronic devices such as PDAs, netbooks and camera phones have displays that are inherently too small to share visual information. Pico Projector technology solves this problem by adding big screen experience for the users. The Pico Projector market is expected to grow in a rapid rate. The mass production of Pico Projectors depends on shrinking the optical and electrical portions of the system. Recent break through in optics development has shown production readiness. However, the production of Pico Projectors is limited by the large sized, expensive and power hungry discrete IC components. This full project will provide proven power management and LED driver semiconductor IPs in the display technology. A key IC component that enables the mass production of Pico Projectors will also be demonstrated as a result of the R&D effort and the collaboration with industry leaders.
