MBI5170 8-Bit Constant Current LED Sink Driver with Gain Control
Load Supply Voltage (V
LED
)
Considering the package power dissipating limits, users had better apply MBI5170 to operate within V
DS
= 0.4V~
1.0V. If V
LED
is higher, for instance, than 5V, V
DS
may be so high that P
D(act)
> P
D(max)
,where V
DS
= V
LED
–
Vf. In this
case, it is recommended to use as low supply voltage as possible or to arrange a voltage reducer, V
DROP
. The
voltage reducer lets V
DS
= (V
LED
–
Vf)
–
V
DROP
. Resistors or Zener diodes can be used as the reducers in the
applications as shown in the following figures.
