Texas Instruments LMR60410-Q1 Synchronous Buck Converter

Texas Instruments LMR60410-Q1 Synchronous Buck Converter is an automotive 36V, 1A converter with low IQ, high-efficiency, and minimized capacitance output. This buck converter operates from 200kHz to 2.2MHz programmable switching frequency range. The LMR60410-Q1 DC-DC converter is designed to step down a higher input voltage to a lower, regulated output voltage efficiently. This converter offers variants with spread spectrum in an ultra-compact, 2.5mm x 2mm, HotRod QFN-9 package, with wettable flanks available. The LMR60410-Q1 device is AEC-Q100 qualified for automotive applications. This LMR60410-Q1 converter is suitable for automotive infotainment and cluster, automotive driver assistance systems, and automotive body requirements.
