Preliminary Datasheet

LP3310

High Performance, Constant Current Switching

Regulator For 8PCS White LED In Series

General Description

The LP3310 is a 1.0MHz PWM boost switching

regulator designed for constant-current white LED

driver applications. The LP3310 can drive a string of

up to 8 white LEDs in series, ensuring uniform

brightness and eliminating several ballast resistors.

The LP3310 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 250mV, which reduces the power

dissipation in the current setting resistor.

Highly integration and internal compensation network

minimizes as 5 external component counts. Optimized

operation frequency can meet the requirement of small

LC filters value and low operation current with high

efficiency.
