IS31BL3212 FOUR CHANNEL CONSTANT CURRENT LED DRIVER January 2012 GENERAL DESCRIPTION The IS31BL3212 provides four regulated current sources, delivers up to 23mA of load current to accommodate four white LEDs. It requires no charge pump, has no noise and significantly improved the efficiency. The serial digital input is used to enable, disable, and set current for each LED with 16 settings down to 0.69mA. A low-current shutdown feature disconnects the load from the input and reduces quiescent current typically 1.0mA. The IS31BL3212 is available in a Pb-free, space-saving 2mm×2mm DFN-8 package.
