LMR14030SDDAR 3.5A, 40V High-Efficiency Buck Switching Regulator IC
The LMR14030SDDAR is a versatile, high-performance 3.5A step-down (buck) DC-DC converter with an integrated high-side MOSFET, designed to deliver efficient and reliable power conversion in industrial, automotive, and battery-powered applications. With a wide input voltage range of 4V to 40V, it is ideal for conditioning power from unregulated sources while maintaining stable and efficient operation.
This device supports adjustable switching frequencies, enabling designers to balance between high efficiency and small solution size depending on the application needs. With a quiescent current of only 40A in sleep mode and 1A in shutdown mode, the LMR14030 significantly enhances battery life in low-power or standby systems. Internal loop compensation simplifies the design process, eliminating the need for external compensation components and minimizing overall BOM count.
