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

由于个人电子设备(如PDA、netbook和拍照手机等)的体积日趋缩小，它们的显示屏太小而无法呈现良好的视觉效果。微投影技术可以提供大屏幕影像，从而很好的解决了这个问题。预计市场对微投影系统的需求将快速增长。 微投影系统的大规模生产和应用取决於光学和电学部份的小型化程度。近期光机部份的突破性进展已经为其量产扫清了障碍，然而，电学部份中分立IC模块尺寸过大、成本过高且功耗太大，仍然限制了微投影系统的推广和应用。 本项目将研发应用於显示系统的功耗管理和LED驱动电路的IP硬核。同时，我们将与业界领先的商业夥伴合作，研发一款关键性的LED光源管理驱动芯片，使微投影系统的大规模生产成为可能。
