Quality Control: Learn More
The Texas Instruments LM3433SQ-NOPB is a high-performance LED driver controller designed for demanding backlight applications. This DC-DC controller utilizes a step-down (buck) topology and offers precise PWM dimming control. Operating with a wide input voltage range of 3V to 5.8V, the device features a switching frequency of up to 1MHz to facilitate compact external component selection. The LM3433SQ-NOPB is housed in a 24-WQFN (4x4) exposed pad package, suitable for surface mount integration. Its robust design allows for operation across an industrial temperature range of -40°C to 125°C (TJ). This component is specifically engineered for applications requiring efficient and accurate LED illumination control.
