Mingjiada Electronics Supply TI LM53601MQDSXRQ1 Automotive Synchronous Buck Regulator
Product Description
The LM53601MQDSXRQ1 is a synchronous step-down (buck) DC-DC converter designed for harsh automotive environments. It integrates a high-efficiency power MOSFET in a compact VQFN package and operates at switching frequencies up to 2.1MHz, and is designed to efficiently step down nominal 12V automotive battery input voltages, typically in the range of 3.5V to 36V, to lower voltages, providing a stable and reliable power supply for a wide range of on-board electronic systems. The LM53601MQDSXRQ1's core strength is its synchronous rectification architecture, which significantly improves conversion efficiency and reduces external component count.
