The LM25145RGYR from Texas Instruments is a synchronous buck DC-DC controller designed for versatile power management applications. It supports a wide input voltage range from 6V to 42V, with an adjustable output voltage capability from 0.8V to 40V. This controller features a switching frequency adjustable from 100 kHz to 1 MHz, allowing for optimization of efficiency and component size.
Key control features include adjustable current limit, enable functionality, frequency synchronization, light load efficiency, power good indication, pre-bias start-up, synchronous rectification, tracking, and adjustable UVLO. The device is housed in a 20-VQFN package with exposed pad, measuring 3.5mm x 4.5mm, and is designed for surface mount, wettable flank mounting.
Additional inherent protection features contribute to robust design, including hiccup mode overcurrent protection, input UVLO with hysteresis, VCC and gate drive UVLO protection, and thermal shutdown protection with hysteresis. The controller also offers a 0.8-V reference with ±1% feedback accuracy and 7.5-V gate drivers for standard VTH MOSFETs.
