Overview
LN9364 80mA 4-Channel Charge Pump White LED Driver with Low Dropout Current Source ■ General Description The LN9364 is a high performance white LED driver.
It integrates current sources and automatic mode selection charge pump.
The part maintains the high efficiency by utilizing an x1/x1.
5 fractional charge pump and low dropout current sources.
The small equivalent x1 mode open loop resistance and ultra-low dropout voltage of current source extend the operating time of x1 mode and optimize the efficiency of Li-ion battery in white LED applications.
The LN9364 supports up to 4 white LEDs and regulates a constant current for uniform intensity.
The part implements a 4-bit DAC for brightness control.
Users can easily configure the LED current from 1.
25mA to 20mA by a serial pulse.
The dimming of white LEDs current can be achieved by applying a pulse signal to the EN pin.
There are totally 16 steps of current could be set by users.
The operating voltage range is 2.
7V to 5.
5V.
