Datasheet

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 40µA in sleep mode and 1µA 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.

Key Features

  • Wide Input Voltage Range: Operates efficiently from 4V to 40V, suitable for industrial and automotive applications.
  • 3.5A Continuous Output Current: Delivers robust power performance for medium to high load systems.
  • Integrated High-Side MOSFET: Reduces external component count and improves efficiency.
  • Adjustable Switching Frequency: Enables optimization between efficiency and component size.
  • Ultra-Low Power Consumption: 40µA sleep mode current and 1µA shutdown current for battery efficiency.
  • Internal Loop Compensation: Simplifies design and minimizes external components.
  • Precision Enable Input: Facilitates accurate control and system power sequencing.
  • Comprehensive Protection: Includes cycle-by-cycle current limit, thermal shutdown, and output overvoltage protection.
  • High Efficiency Operation: Optimized for both light and heavy load conditions.
  • Compact SOIC-8 Package: Thermally enhanced for improved heat dissipation and small PCB footprint.
