More Information

The LM3630A is a current-mode boost converter which supplies the power and controls the current in up to two strings of 10 LEDs per string. Programming is done over an I2C-compatible interface. The maximum LED current is adjustable from 5 mA to 28.5 mA. At any given maximum LED current the LED brightness is further adjusted with 256 exponential or linear dimming steps. Additionally, pulsed width modulation (PWM) brightness control can be enabled allowing for LED current adjustment by a logic level PWM signal.
