Combination of linear dimming and PWM dimming

Linear dimming and PWM dimming can be combined, as shown in Figure 23, thereby ensuring advantageous output

current accuracy throughout the range from 100% rated current to very small currents.

more, linear dimming is used. If Io is Io’ or less, PWM dimming is used. The high level of the signal for PWM dimming is

adjustments to smaller currents than PWM dimming alone and achieves control with better output current accuracy than

linear dimming alone.
