dd233  5-30ma可設置小體開關型4信道驅動IC

     the dd233 is a 4-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 dd233 directly determines output current by each channel in low bit-to-bit skew, it is ideal for driving led whose light intensity is proportional to the current passing through them, not the  voltage across their terminals. the enable provides the low power stand by function for mobile applications.

this configuration eliminates the need of external capacitors and inductances. with an input voltage range of 2.7v to 6v, so the device can work in general battery system. the value of constant current can be varied using an external resistor (iout)

     features: constant current output, 5~30ma. supply voltage vdd is 2.7v to 6v. bit-to-bit :±3.0% (max) @ iout= 5 ~ 30ma. 8-pin sop8 or msop8 package.

      applications:digital cameras. portable mp3 players. white led display backlighting. cellular telephones. handheld computers.  pagers. personal digital assistant.  e-books and sub notebooks
