1. GENERAL DESCRIPTION

The AP2063 is a white LED driver IC for camera flash applications in portable equipment. The device

integrates a current mode synchronous boost DC-DC converter and maximum 2A current sources. The internal

boost DC-DC converter integrates a switching FET and synchronous rectifier, and supports a small size

multilayer inductor with 4MHz switching frequency. The internal current sources allow for grounded cathode

connections for easier heat dissipation and simple LED arrangement. The AP2063 includes seven protections

that are inductor current limitation, input voltage detection, over voltage protection, under voltage lock out,

device thermal protection, LED open/short protection and output-ground short protection to avoid significant

system problems. Flash current, torch current, inductor limit current and flash on-time is programmable

through I

utilize less board space.
