Document number: DS40917 Rev. 1 - 3 14 of 16 www.diodes.com April 2018 © Diodes Incorporated AP3606/AP3607 Digital Dimming Operating Diagram (Note 3) Note 3: The dimming control can be achieved by applying a pulse to the EN p in. When the low level duration time of pulse is between tLO(MIN) and tLO(MAX), and the high level duration time is larger than tHI(MIN), the LED current will decrease 1/16. If the low level duration time is larger th an tSHDN(MAX), the IC will be turned off. When AP3606/AP3607 is powered on, the WLED is in full brightness. And it will keep maximum current until the pulse is detected. After 15 pulses the WLED current decreases to 1/16 of full brightness. It will increase to full brightness if a pulse is added to EN pin then.
