+title: TI LM3560 Synchronous Boost Flash Driver

+
+description: |
+  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.
