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.
