TB62706BNG/BFG
TOSHIBA Bi- CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC
TB62706BNG, TB62706BFG
16BIT SHIFT REGISTER, LATCHES & CONSTANT CURRENT DRIVERS
The TB62706BNG, TB62706BFG are specifically designed for LED
and LED DISPLAY constant current drivers.
This constant current output circuits are able to set up external
resistor (IOUT = 5~90 mA). (Note)
These devices are monolithic integrated circuit designed to be used
together with Bi- CMOS process.
The devices consist of 16bit shift register, latch, AND- GATE and
Constant Current Drivers.
These products are Pb free.

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.
