 Mean Well&#x27;s AP Constant Current Driver is a good example shown below: Higher current ratings do make the LED brighter, but if not regulated, the LED will draw more current than it is rated for. It is a high efficiency boost converter that operates from 1 or 2 NiMH or alkaline cells and generates 350mA of constant current with up to 4V of compliance. Calculations: - LED current is set by R3, it is approximately equal to: 0.5 / R3. Found inside – Page 702LED drivers with internal PWM in addition to constant current drive (Fig. ... of driver allows for significant reduction of the data flow over driver IC. SOIC8-EP. In a nutshell, we can say that a small increase in applied forward voltage can greatly increase the current through the LED.
