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
