LP3954 General 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 micro SMD package together with minimum number of external components is a best fit for handheld devices.
