TEXAS INSTRUMENTS LP39542TL/NOPB LED Driver, Boost Step Up, 2.7-5.5V input, 1 Output, 2MHz switch-freq., 5.3V/400mA out, DSBGA-36
LP39542 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 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 I2C interface allows easy control of LP39542. Small DSBGA package together with minimum number of external components is a best fit for handheld devices.
