The IS31BL3229 with a smart charge-pump circuit is a
parallel white-LED driver with eight matched 20mA
current outputs. It can supply a total output current of
160mA over an input voltage range of 2.7V to 5.5V.
IS31BL3229 typically draws less than 1µA when placed
in shutdown, and 0.7mA when operating in the no-load
and 1X mode condition. If any of the outputs are not
used, leave the pin(s) unconnected. Brightness can be
controlled by simple-series-control techniques and
external PWM signal.
IS31BL3229 is available in QFN-20 (3mm × 3mm). It
operates from 2.7V to 5.5V over the temperature range
of -40°C to +85°C.
