GENERAL DESCRIPTION
The IS31BL3230 provides eight regulated current sources, each delivers up to 40mA of load current with careful selection of external sense resistors, all outputs at the IS31BL3230 may be connected in parallel to enable the current through the LED to be as high as 320mA.
The IS31BL3230 does not include a charge pump and therefore has no noise and significantly improved the efficiency. The external resistor, RSET1, determines the constant current output of ports LED1 thru LED4, while resistor RSET2 determines the constant current output of ports LED5 thru LED8.
