LP3361

Preliminary Datasheet LP3361 6-Channel Constant Current White LED Driver General Description The LP3361 is a low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs. It supports 6 white LEDs with regulated constant current for uniform intensity. The LP3361 maintains low dropout current regulators. The LP3361 requires a 45mV dropout at a 20mA load on each output to match the LED brightness. The brightness of LEDs can be tuned through a pulse width modulated signal at the PWM pin,the PWM frequency from 200Hz to 10KHz and the Duty from 0 to 100%. The LP3361 is available in a TDFN-10 package.
