LM3556 Datasheet - Texas Instruments

LM3556 1.5-A Synchronous Boost LED Flash Driver

The LM3556 is a 4-MHz fixed-frequency synchronous boost converter plus 1.5-A constant current driver for a high-current white LED. The high-side current source allows for grounded cathode LED operation providing flash current up to 1.5 A. An adaptive regulation method ensures the current source rema.

LM3556 Features

* 1 Grounded Cathode LED Operation for Improved Thermal Management

* 1.5-A High-Side Current Source for Single LED

* Accurate and Programmable LED Current from 46.9 mA to 1.5 A

* > 85% Efficiency in Torch Mode (at 100 mA) and Flash Mode (at 1 A to 1.5 A)

* Smal
