High Performance, Constant Current Switching
Regulator For 8PCS White LED In Series
General Description
The LP3311S is a 1MHz PWM boost switching regulator
designed for constant current white LED driver applications.
The LP3311S can drive a string of up to 8 white LED in
series, ensuring uniform brightness and eliminating several
ballast resistors. The LP3311S implements a constant
frequency 1MHz PWM control scheme. The high frequency
PWM operation also saves board space by reducing
external component size. To improve efficiency, the
feedback voltage is set to 200 mV, 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.
