DM11A SITI [Silicon Touch Technology Inc.], DM11A Datasheet - Page 13

• Manufacturer Part Number: DM11A
• Description: 8-bit Constant Current LED Driver
• Manufacturer: SITI [Silicon Touch Technology Inc.]

Outputs Delay
this effect, DM11A is designed to have a constant unit of delay (around 2.5ns) between outputs. The
delay sequence for every output goes like this: OUT0 (no delay)
OUT2
Global Brightness Control
of global brightness control effect, two methods could be utilized. One is providing PWM signal
synchronized on latch pulse to modulate the output enable terminal (EN pin). The other is to adjust
the Rrext value or voltage drop across the external resistor. Please see the reference circuit below:
8-bit Constant Current LED Driver
Large in-rush currents will occur when the system activates all the outputs at once. To reduce
DM13A has no built-in global brightness control feature. In order to obtain a lower resolution
