SNOSB43C – SEPTEMBER 2011 – REVISED NOVEMBER 2016 LM3560 Synchronous Boost Flash Driver
With Dual 1-A High-Side Current Sources (2-A Total Flash Current)
1 Features 3 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. 1 Dual High-Side Current Sources Allow for
Grounded Cathode LED Operation
Accurate and Programmable LED Current from
31.25 mA to 2 A
Independent LED Current Source Programmability
Up to 90% Efficient
Ultra-Small Solution Size: < 26 mm2
Four Operating Modes: Torch, Flash, Privacy …
