DESCRIPTION

LP3954 is an advanced lighting management unit for

handheld devices. It drives any phone lights including

display backlights, RGB, keypad and camera flash

LEDs. The boost DC-DC converter drives high

current loads with high efficiency. White LED

backlight drivers are high efficiency low voltage

structures with excellent matching and automatic fade

in/ fade out function. The new stand-alone command

based RGB controller is feature rich and easy to

configure. Built-in audio synchronization feature

allows user to synchronize the color LEDs to audio

input. Integrated high current driver can drive camera

flash LED or motor/vibra. Internal ADC can be used for ambient light or temperature sensing. The flexible

SPI/I2C interface allows easy control of LP3954.

Small DSBGA package together with minimum

number of external components is a best fit for

handheld devices.
