LP5569RTWR Description
The LP5569RTWR is a programmable, easy-to-use 9 -channel I2C LED driver that may be used to create various lighting effects. The LED driver includes an internal SRAM memory for user-programmed sequences as well as three programmable LED engines for operation without the usage of a processor. When the processor is put into sleep mode, autonomous functioning minimizes system power usage.
Even with a 2.5 -V input voltage, a high-efficiency charge pump can drive LEDs with high VF. By autonomously selecting the appropriate charge-pump gain depending on LED forward voltage needs, the LP5569RTWR LED driver maintains good efficiency throughout a wide operating voltage range. When LEDs are not active, the LP5569RTWR gadget enters power-saving mode, significantly reducing idle-current usage.
