tb62725bpg/bfg/bfng? 2005-04-20? 13 ? notes operation may become unstable due to the electromagnetic interference caused by the wiring and other phenomena. to counter this, it is recommended that the ic be situated as close as possible to the led module. if overvoltage is caused by inductance between the led and the output terminals, both the led and the terminals may suffer damage as a result. there is only one gnd terminal on this device when the inductance in the gnd line and the resistor are large, the device may malfunction due to the gnd noise when output switching by the circuit board pattern and wiring. to achieve stable operation, it is necessary to connect a resistor between the rext terminal and the gnd line. fluctuation in the output waveform is likely to occur when the gnd line is unstable or when a capacitor (of more than 50 pf) is used. therefore, take care when designing the circuit board pattern layout and the wiring from the controller. this application circuit is a reference example and is not guaranteed to work in all conditions. be sure to check the operation of your circuits. this device does not include protection circuits for over voltage, over current or over temperature. if protection is necessary, it must be incorporated into the control circuitry. the device is likely to be destroyed if a short- circuit occurs between either of the power supply pins and any of the output terminals when designing circuits, pay special attention to the positions of the output terminals and the power supply terminals (v dd and v led ), and to the design of the gnd line.
