LP3958规格书详情
描述 Description
LP3958 is a Lighting Management Unit for portable applications. 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 voltage 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 current mode. External PWM control can be used for any selected outputs. The device is controlled through 2-wire low voltage I2C compatible interface that reduces the number of required connections. LP3958 is offered in a tiny 25-bump DSBGA package.
