- LED Flash-Protection FeaturesPDF, 33 Kb, Datei veröffentlicht: Aug 23, 2017
Modern LED camera flash drivers are feature-rich and power dense. Capable of delivering over 2 A ofcurrent to dual LEDs in packages as small as 1.69 mm Г— 1.31 mm, flash LED drivers require built-in safetyand protection features to maintain long-term device and system health. Devices such as the LM3643,LM3644, LM3648, LM3646, LM3642, LM36010, and LM36011 all provide many specific protection
