The pwm output switches between −1/2 and +1/2
Webb18 nov. 2024 · Real PWM dimming allows a broader range of PWM frequency. A significant positive with the real PWM dimming is its ability to preserve the white point of the LED output. It also permits a high level of the reference voltage, which is above offset errors. All uPowerTek drivers integrate MCU to work with PWM dimming. WebbFigure 2.
