The LM3433SQ/NOPB from Texas Instruments is a DC/DC buck constant current controller designed for illuminating high-power LEDs. It features an adaptive constant on-time architecture, enabling the use of small passive components and eliminating the need for an output capacitor while maintaining low LED ripple current.
Key electrical specifications include an operating input voltage range of -9V to -14V and a maximum supply voltage of 14V. The device offers an output current greater than 6A and a switching frequency up to 1MHz. It supports PWM dimming for brightness control and has a quiescent current of 1mA typical.
This LED driver is suitable for various applications, including LCD backlighting, projection systems, solid-state lighting, and automotive lighting. It is housed in a 24-WQFN (4x4) package and features a surface mount type.
The controller's high-frequency PWM dimming capability allows for digital color temperature control and brightness adjustments. Additional features include thermal shutdown and VCC under-voltage lockout.
