概觀

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.
