2.0A Highꢀside LED Driver for Camera Flash with I²C

GENERAL DESCRIPTION

The AP2061 is a white LED driver IC for camera flash applications in portable equipments. 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. AP2061

includes eight protections that are LED thermal detection, 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 I²C interface. The device uses

a small size package (CSP: 1.6mm x 1.6mm, 0.4mm pitch, 16pins) to utilize less board space.
