Interface ICs vs. Direct Dimming: When to Use Each
Direct dimming is well suited for simpler lighting designs where the driver IC directly accepts a known dimming method and the system operates within a controlled environment. This approach can reduce component count when compatibility requirements are limited and dimming performance is well defined.
Lighting interface ICs are ideal for designs that must support multiple dimming standards or unknown dimming inputs. By automatically detecting PWM, analog, or resistive dimming signals and converting them into a clean PWM output, interface ICs simplify system integration, improve dimming accuracy, and enable broader compatibility. This makes them especially valuable in professional, retrofit, or multi‑region lighting applications where flexibility and robustness are critical.
