CONFIDENTIAL - Target Datasheet SM5306 High-Efficiency Dual-String with up to 10-WLED White LED Driver Description The SM5306 is a current mode boost converter which supplies the power and controls current in up to two strings of 10 LEDs per string. Programming is done over an I2Ccompatible interface. The maximum LED current is adjustable from 5mA to 28.5mA. At any given maximum LED current the LED brightness is further adjusted with 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. The boost switching frequency is programmable at 500kHz for low switching loss performance or 1MHz to allow the use of tiny low profile inductors.
