DESCRIPTION
The PT6907 is a buck LED driver which has linear dimming function with normal switch ON/OFF. While turning-on the switch first time, the LED current will increase from the minimum value to the maximum current during about 9 seconds. The PT6907 builds-in exponential algorithm and the LED’s brightness changes smoothly and linearly. During the dimming processing, you can turn-off the switch when the LED’s brightness reaches the level you want. The PT6907 can remember and hold the status for a certain time which is programmable after turned-off.
