5mw laser emitting diode drive circuit

It uses an APC (Automatic Power Control) drive circuit, which actively monitors and regulates the laser diode's output current to keep brightness stable and consistent even as supply voltage and temperature fluctuate. ROHM offers laser diodes (LDs) for Light Detection and Ranging (LiDAR). This application note will introduce ROHM's LD line-up and show how...
