DD231 drivers equivalent, 3-channel constant current led drivers.
․Constant Current Output, 5~30mA. ․Supply Voltage VDD is 3V to 5V. ․Bit-to-Bit : ± 3.0% (Max) @ IOUT = 5 ~ 30mA. ․Only Need One External Resistor, No Other External Parts.
․White LED Display Backlighting ․Cellular Telephones ․Handheld Computers ․Digital Cameras ․Portable MP3 Players ․Pagers .
The DD231 is a 3-channel constant current LED driver. It’s designed to operate as a constant-current sink to drive the LEDs with an external resistance in low power environment. Because the DD231 directly determines output current by each channel in .
