LED DRIVER TB6270X SERIES APPICATION NOTE
[1] Output current (I
OUT
)
I
OUT
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 (V
O
).
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,
V
LED
(total supply voltage) = V
CE
(T
r
V
sat
) + V
f
(LED Forward voltage) + V
O
(I
C
supply voltage)
When the total supply is too high considering the power dissipation of this device, an additional R can decrease the
supply voltage (V
O
).
[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.
