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