High Speed Triple Laser Diode Drivers ISL58315 The ISL58315 is a high-speed, triple-output laser diode driver (LDD) for laser scanning projector systems, which require three channels modulated at high speed with independent current control. Features • High-speed, triple-output laser diode driver supporting up to 720-pixel HD resolution Each output channel provides laser-independent current • Up to 1A of peak current output control for threshold and color DACs. Separate scale DACs allow independent scaling of both threshold and color DAC output values. This allows control of projector brightness and can be used to simplify automatic power calibration (APC) for • Fast output switching speeds with pulse rise/fall times of 1ns to 2ns for crisp pixels • Intersil patented laser vo [ ... ]
