Texas Instruments LM3000ASQX-NOPB is a highly efficient, dual-phase, synchronous buck controller designed for step-down DC-DC conversion. This device operates with a wide input voltage range of 3.3V to 5.5V and features a switching frequency adjustable from 200kHz to 1.5MHz. The LM3000ASQX-NOPB supports a maximum duty cycle of 85% and includes advanced control features such as programmable current limit, enable, frequency control, power good signal, soft start, and tracking. Its output configuration is positive, and it drives external power transistors. The dual-phase operation and synchronous rectification contribute to improved efficiency and reduced output ripple, making it suitable for demanding applications in computing, networking, and industrial power systems. This component is supplied in a 32-WQFN (5x5) package on tape and reel.
