High Performance, Constant Current Switching Regulator

For 9PCS White LED

General Description

The LP3303 is a 1.0MHz PWM boost switching

regulator designed for constant- current white LED

driver applications. The LP3303 can drive a string of

up to 8 white LEDs from a 3.6V in series, ensuring

uniform brightness and eliminating several ballast

resistors. The LP3303 implements a constant

frequency 1.0MHz PWM control scheme. The high

frequency PWM operation also saves board space

by reducing external component sizes. To improve

efficiency, the feedback voltage is set to 200mV,

which reduces the power dissipation in the current

setting resistor.
