The SD3303A with LED Drivers SOT-23-6 RoHS is a small size, low-cost, high-efficiency, and RoHS compliant LED driver with integrated switch mode topology designed and manufactured by SHOUDING. It includes a low side current-mode controller, two N-Channel MOSFETs, sample-and-hold circuit, and a linear regulator. It has a wide input voltage range (from 3V to 18V) that makes it suitable for a variety of applications including automotive, industrial, and consumer LED lighting products. The SD3303A is designed to drive high-power LEDs with an input voltage up to 18V. It has an LED dimming ratio of up to 1000:1 and a maximum output current of 1.8A. The integrated thermal protection prevents damage due to high temperature and ensures reliable operation. The SD3303A also has an auto-adjusting standby current that improves efficiency and efficiency as low as 0.5%. It is RoHS compliant and is available in a compact 6-pin SOT-23-6 package.
