LM3560 Overview
The LM3560 is a 2-MHz fixed frequency synchronous boost converter with two 1000-mA constant current drivers for high-current white LEDs. The dual highside current sources allow for grounded cathode LED operation and can be tied together for providing flash currents at up to 2 A through a single LED. An adaptive regulation method ensures the current for each LED remains in regulation and maximizes efficiency.
