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.
