Dimming Control

1.Using a PWM Signal to CE Pin

When adding the PWM signal to CE pin, the ACE714C is turned on or off by the PWM signal, so the

LEDs operate at either zero or full current. The average LED current increase proportionally with the

duty cycle of the PWM signal.

2.Using a DC Voltage to FB Pin

From the Figure 2, we can add a DC voltage to FB pin, we adjust the LED current by changing the DC

voltage, which control the brightness, DC voltage range is from 0V to 2V.
