LM25141QRGERQ1 General Description

With a focus on high-voltage, wide-VIN step-down regulator applications, the LM25141QRGERQ1 sets itself apart as a synchronous buck controller that combines cutting-edge technology with efficient performance. Featuring peak current-mode control, this controller offers a range of advanced functions including line feed-forward, cycle-by-cycle current limiting, and simple loop compensation for enhanced operation. Its versatility is evident in the two selectable switching frequencies (2.2 MHz and 440 kHz), gate drivers with slew rate control for EMI reduction, and skip cycle mode that boosts low power efficiency during light or no-load conditions. Moreover, the LM25141QRGERQ1 includes key features such as frequency synchronization, cycle-by-cycle current limit, hiccup-mode fault protection, and a power-good output, ensuring reliable and robust performance in demanding environments. The device's AEC-Q100 qualification for automotive applications, coupled with a VQFN-24 package with wettable flanks, makes it a compelling choice for engineers seeking a high-quality buck controller solution
