5 / 9 page ACE714C Max. 3MHz, Variable Frequency Step-up DC/DC Converter VER 1.2 5 Typical Performance Characteristics Application Information 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. |
