DM134、DM135、DM136 點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC. 16-Bit Constant Current LED Drivers -13- Version :A.013 System Configuration Example [1] Output current (IOUT) Sink current is set by the external resistor as shown in the figure of Iout vs. Rext. [2] LED supply voltage (VLED) setup VLED = VCE ( Tr Vsat ) + Vf ( LED forward voltage ) + VO ( IC supply voltage) To prevent too much power from dissipating by the higher V LED of the device, an additional R can be used to reduce the V out when the outputs consume current is as follows: R = (max)*(max) (min) BitI VVVV O OfCELED −−− Note This device has only one ground pin shared by signal, output sink current, and power ground. It is advisable to pattern the ground layout with mini mized inductance so that the switching noise induced by the input signals and the output sink current would not cause chip malfunction. To prevent drivers’ outputs from damaging by overshoot stresses, it is also advisable not to turn off the drivers and scan transistors simultaneously. For the QFN package, the IC’s thermal pad, which is internally connected to the bottom side of chip, should be connected to GN D. In addition, a good PCB layout pattern of the thermal pad is required in order to have a better performance in thermal effect.
