Three-channel driver enables handheld laser pico projectors
The MAX3600 three-channel laser driver lets designers build high-resolution laser pico projectors with WVGA or SVGA resolutions into smaller-form-factor devices, overcoming digital light processor (DLP) and liquid-crystal-on-silicon (LCoS) technology limitations. By integrating discrete RGB laser drivers into a single 5 x 5-mm chip, the device consumes 30% less power, 75% less real estate, and 25% less cost than discrete designs, making it well suited for compact battery-operated handheld devices.
The driver integrates the functionality needed to easily interface a digital 10-bit RGB video source to industry-standard low-power RGB laser diodes. Its three 10-bit RGB DACs, which read video data from the host device’s 10-bit RGB bus, allow system designers to precisely control laser current while generating billions of colors and contrast ratios of 5,000:1 and higher.
For operation with synthetic green lasers, the driver provides a periodic off function and a fourth output with a random-noise generator. The device also has 2-ns output switching time and 8-bit gain and offset functions, along with serial ports and registers, to make image adjustments quick and simple. Packaged in a 40-pin TQFN, the driver is fully specified over a 0° to 70°C range. (From $8.93 ea / 1,000 — available now.)
