LMR14030SQDDARQ1 Description

Short technical summary and product information.

The LMR14030SQDDARQ1 from Texas Instruments is an automotive-grade DC DC switching regulator designed for step-down conversion. It operates with an input voltage range of 4V to 40V and can deliver up to 3.5A of continuous output current.

 

This device offers an adjustable output voltage, controllable from 1V to 30V. It features a switching frequency that can be adjusted from 200kHz to 2.5MHz, with a spread spectrum option for reduced EMI. The regulator includes features such as over-current protection, soft start, and UVLO adjustment.

 

Packaged in an 8-SO PowerPad (8-PowerSOIC), the LMR14030SQDDARQ1 is suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ), making it robust for automotive environments. The device also boasts an ultra-low quiescent current of 40µA.
