1 / 28 page  LP3958 Lighting Management Unit with High Voltage Boost Converter General Description LP3958 is a Lighting Management Unit for portable applica- tions. It is used to drive display backlight and keypad LEDs. The device can drive 5 separately connected strings of LEDs with high voltage boost converter. The keypad LED driver allows driving LEDs from high volt- age boost converter or separate supply voltage.The MAIN and SUB outputs are high resolution current mode drivers. Keypad LED outputs can be used in switch mode and cur- rent mode. External PWM control can be used for any se- lected outputs. The device is controlled through 2-wire low voltage I 2C compatible interface that reduces the number of required connections. LP3958 is offered in a tiny 25-bump micro-SMD package. Features n High efficiency boost converter with programmable output voltage n 2 individual drivers for serial display backlight LEDs n 3 drivers for serial keypad LEDs n Automatic dimming controller n Stand alone serial keypad LEDs controller n 3 general purpose IO pins n 25-bump micro SMD Package: (2.54mm x 2.54mm x 0.6mm) Applications n Cellular Phones and PDAs n MP3 Players n Digital Cameras Typical Application 20175570 February 2006 © 2006 National Semiconductor Corporation DS201755 www.national.com |
