Application Information
Dimming Control
1. Using a PWM Signal to CE Pin
When adding the PWM signal to CE pin, the ACE714 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. The frequency range of the PWM signal is from 1 kHz to 300KHz.
2. Using a DC Voltage
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.
