HYSTERETIC LED DRIVER WITH LOW END LINEARIZATION |
摘要 |
Systems and methods for smoothing out visual effects of Light Emitting Diodes (LEDs). An example circuit includes one or more LEDs, a hysteretic controller circuit, and a linearization circuit. The hysteretic controller circuit supplies current to the LEDs when a Pulse Width Modulation (PWM) signal is in a first state and the linearization circuit drives the current supplied by the hysteretic controller circuit to an off state when the PWM signal transitions to a second state.
