3 Description
The LP5569 device is a programmable, easy-to-use
9-channel I2C LED driver designed to produce lighting
effects for various applications. The LED driver is
equipped with an internal SRAM memory for userprogrammed
sequences and three programmable
LED engines, which allow operation without
processor control. Autonomous operation reduces
system power consumption when the processor is put
in sleep mode.
A high-efficiency charge pump enables the driving of
LEDs with high VF, even with 2.5-V input voltage. The
LP5569 LED driver maintains good efficiency over a
wide operational voltage range by autonomously
selecting the best charge-pump gain based on LED
forward voltage requirements.
The LP5569 device enters power-save mode when
LEDs are not active, lowering idle-current
consumption considerably. A flexible digital interface
allows the connection of up to eight LP5569 devices
with a unique I2C slave address for each device in
the same system, which supports synchronization of
the lighting effects among all devices.
