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.
