National Semiconductor Corporation introduced the world’s smallest backlight light emitting diode (LED) driver that controls lighting applications in handheld devices, including cellular phones, digital still cameras, gaming devices and MP3 players.
Housed in a tiny micro SMD package, the LP3954 advanced lighting management unit integrates two backlight drivers, a dual red-green-blue (RGB) LED controller, a Flash LED driver and an analog-to-digital converter (ADC) on a single chip. The integrated, magnetic boost DC-DC converter efficiently drives high current loads over a wide battery voltage range.
