LMR14050SSQDDARQ1 Description

Short technical summary and product information.

The LMR14050SSQDDARQ1 from Texas Instruments is an automotive-grade SIMPLE SWITCHER® power converter designed for step-down applications. This device operates with an input voltage range from 4V to 40V and can deliver up to 5A of continuous output current. It features an adjustable output voltage, controllable from 0.8V to 28V.

 

Key electrical characteristics include an adjustable switching frequency ranging from 200kHz to 2.5MHz, allowing for design flexibility and optimization for efficiency or solution size. The regulator boasts an ultra-low quiescent current of 40µA, making it suitable for power-sensitive automotive applications. It incorporates features such as frequency synchronization, light load efficiency, over-current protection, power good signal, pre-bias start-up, soft start, and adjustable UVLO.

 

The LMR14050SSQDDARQ1 utilizes current mode control and includes internal compensation for ease of use. An integrated 90mΩ high-side MOSFET contributes to its efficiency. The device also offers a spread spectrum option to reduce electromagnetic interference (EMI).

 

Packaged in an 8-SO PowerPad (8-PowerSOIC) surface-mount package, this component is qualified for automotive applications, meeting AEC-Q100 standards with a temperature grade of 1 (-40°C to 125°C ambient operating temperature).
