概述

The AS5826 is a simple and robust constant-maxi-current regulator designed to provide a cost-effective solution for driving high-voltage LEDs in LED lamp applications. The AS5826 is equipped with a proprietary control mechanism to improve the utilization of high-voltage LEDs. It provides low pin-count SOP-8 package with customized current setting to meet various application requirements. In addition, the AS5826 also provides a thermal regulation protection, instead of traditional thermal shutdown, to suppress the rise of the temperatures in LED lamps and prevent the LED lamps from flickering. It is most suitable for designs seeking superb cost/performance ratio solutions, in parallel, offering skillful fulfillment of most safety requirements in LED general lighting applications aiming at direct replacement of commercial or residential incandescent lamps alone and without the need of replacing original light fixtures.
