LMR14030QDPRRQ1 Description

Short technical summary and product information.

The LMR14030QDPRRQ1 from Texas Instruments is an automotive-grade SIMPLE SWITCHER® power converter. This device is a 40V, 3.5A step-down (buck) converter designed for efficient power management in automotive applications.

 

Key electrical specifications include an input voltage range of 4V to 40V and an adjustable output voltage from 1V to 30V. It delivers up to 3.5A of continuous output current. The converter operates with an ultra-low quiescent current of 40µA, making it suitable for power-sensitive designs. Its switching frequency is adjustable from 200kHz to 2.5MHz, with options for frequency synchronization and spread spectrum for reduced EMI.

 

Designed for ease of use, the LMR14030QDPRRQ1 features internal compensation, soft start, and over-current protection. It is AEC-Q100 qualified for automotive applications, operating within a junction temperature range of -40°C to 125°C.

 

The component is available in a 10-WSON (4x4 mm) package and is designed for surface mount applications. Its features like adjustable switching frequency, spread spectrum, and low quiescent current make it a versatile choice for various automotive power supply designs.
