Description

The LM27966SQ is a highly integrated charge-pump-based display LED driver. The device can drive up to 6 LEDs in parallel with a total output current of 180mA. It provides excellent efficiency without the use of an inductor by operating the charge pump in a gain of 3/2, or in Pass-Mode.

The features of LM27966SQ can be summarized as:(1)91% Peak LED Drive Efficiency; (2)No Inductor Required; (3)0.3% Current Matching; (4)Drives 6 LEDs with up to 30mA per LED; (5)180mA of total driver current; (6)I2C Compatible Brightness Control Interface; (7)Adaptive 1x- 3/2x Charge Pump; (8)Resistor-Programmable Current Settings; (9)External Chip RESET Pin (RESET); (10)Extended Li-Ion Input: 2.7V to 5.5V; (11)Small low profile industry standard leadless package,LLP 24: (4mmx 4mm x 0.8mm).

The absolute maximum ratings of LM27966SQ are:(1)VIN pin voltage:-0.3V to 6.0V; (2)SCL, SDIO, VIO, RESET pin voltages:-0.3V to (VIN+0.3V)w/ 6.0V max; (3)IDx Pin Voltages:-0.3V to (VPOUT+0.3V)w/ 6.0V max; (4)Continuous Power Dissipation:Internally Limited; (5)Junction Temperature (TJ-MAX):150°C; (6)Storage Temperature Range:-65°C to +150°C; (7)ESD Rating Human Body Model:2.0kV.
