Utmost care is necessary in the design of the output line, VCC (VDD) and GND line since IC may be destroyed due to short- circuit between outputs, air contamination fault, or fault by improper grounding.

LED DRIVER TB6270X SERIES APPICATION NOTE [1] Output current (IOUT) IOUT is set by the enternal resistor (R- EXT) as shown in Fig.1. [2] Total supply voltage (VLED) This device can operate 0.4~0.7V (VO). When a higher voltage is input to the device, the excess voltage is consumed inside the device, that leads to power dissipation. In order to minimize power dissipation and loss, we would like to recommend to set the total supply voltage as shown below, VLED (total supply voltage) = VCE (Tr Vsat) + Vf (LED Forward voltage) + VO (IC supply voltage) When the total supply is too high considering the power dissipation of this device, an additional R can decrease the supply voltage (VO). [3] Pattern layout This device owns only one ground pin that means signal ground pin and power ground pin are common. If ground pattern layout contains large inductance and impedance, and the voltage between ground and LATCH, CLOCK terminals exceeds 2.5 V by switching noise in operation, this device may miss- operate. So we would lile you to pay attention to pattern layout to minimize inductance.
