The LM2755 is a charge-pump-based, constant-current LED driver capable of driving 3 LEDs with a total output current up to 90mA. It features an I2C-compatible interface for programmable timing and brightness, offering 32 exponential dimming steps with an 800:1 dimming ratio. The device operates in gains of 1x or 3/2x to maximize efficiency over a wide input voltage range of 2.7V to 5.5V without the need for an inductor.
Temp Range-30 to 85°C
