Overview
Preliminary Datasheet LP3322 High Performance, Constant Current Switching Regulator For 10PCS White LED In Series General Description Features The LP3322 is a 1.
1MHz PWM boost switching regulator designed for constant- current white LED driver applications.
The LP3322 can drive a string of up to 10 white LEDs in series or 3s9p LEDs from 3.
6V, ensuring uniform brightness and eliminating several ballast resistors.
The LP3322 implements a constant frequency 1.
1MHz 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 and 300mV, which reduces the power dissipation in the ...
