LP3360-MSF

Preliminary Datasheet LP3360 4-Channel Constant Current White LED Driver General Description The LP3360 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 4 white LEDs with regulated constant current for uniform intensity. The LP3360 maintains low dropout current regulators. The LP3360 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 LP3360 is available in a SOT23-6 or MSOP-8 package.
