Texas Instruments LM3433SQX-NOPB is a DC/DC controller designed for LED driving applications. This device features a step-down (buck) topology and supports Pulse Width Modulation (PWM) dimming for precise brightness control. Operating with a supply voltage range of 3V to 5.8V, it offers a high switching frequency of 1MHz, enabling efficient power conversion and compact external component selection. The LM3433SQX-NOPB is housed in a 24-WQFN (4x4) package with an exposed pad for enhanced thermal performance, suitable for surface mount assembly. Its design is optimized for applications such as LED backlighting in displays and general illumination systems. The component is supplied on tape and reel for automated manufacturing processes.
