AP2071AEN Datasheet | Asahi Kasei Microdevices

Description The AP2071AEN is a white LED driver IC for camera flash, using EDLC (Electronic Double Layer Capacitor) in portable equipment. The AP2071AEN integrates a current mode synchronous boost DC-DC converter and four maximum 2A current sources (maximum 8.0A total). The internal boost DC-DC converter integrates a switching FET and synchronous rectifier, and supporting small size multilayer inductor with 2MHz switching frequency. An integrated EDLC voltage control circuit and a charge current control circuit makes the AP2071AEN most suitable for EDLC charge systems. The AP2071AEN also includes eight protections that are an under voltage lock out, EDLC cell short/open protection, thermal detection, LED open/short detection, LED thermal protection, output-ground short protection, inductor current limitation and flashing time limitation to avoid significant system problems.
