Over-Current Protection Over-Temperature Protection Compatible Interface Under-Voltage Lockout LED Open and Short Protection and Detection • 95% Peak Efficiency Buck-Boost Converter NVM Memory for Calibration Data and Standalone Usage without Control Soft Start The LM3549 is a high power LED driver with up to 700mA output current. It has three constant current LED drivers and a buck boost SMPS for driving RGB LEDs with high efficiency. LED drivers are designed for sequential drive so only one driver can be enabled at a time. LED driver output current settings can be stored to integrated non-volatile memory which allows standalone operation without interface. Non-volatile memory is rewritable so current setting can be changed if needed.
