Texas Instruments LM3552SD is a DC-DC regulator featuring a step-up (boost) topology for LED driving applications. This device is engineered to provide a regulated output of up to 1A specifically for camera flash functionality. The LM3552SD integrates internal switching capabilities, simplifying design and reducing component count. With a fixed switching frequency of 1.25MHz, it enables a compact solution when paired with its 14-WSON (4x4) package. The operating temperature range is -40°C to 85°C (TA), suitable for demanding environments. It operates from a supply voltage range of 2.7V to 5.5V. This component is commonly utilized in mobile devices and digital cameras for its efficient and high-current LED driving capabilities. The device is supplied in a Tape & Reel (TR) package.
