LV14340DDAR Description

Short technical summary and product information.

The LV14340DDAR from Texas Instruments is a versatile 40V, 3.5A step-down switching regulator designed for power conditioning from unregulated sources in industrial and automotive applications.

 

Key electrical specifications include a wide 4V to 40V input range, 3.5A continuous output current, and an adjustable switching frequency from 200kHz to 2MHz, allowing optimization for efficiency or component size. It features a 100ns minimum on-time and a low 1µA shutdown current.

 

Designed for ease of use, the LV14340DDAR incorporates internal compensation, minimizing external component count and simplifying loop compensation design. A precision enable input aids in regulator control and system power sequencing. Protection features include cycle-by-cycle current limit, thermal sensing and shutdown, and output overvoltage protection.

 

The device is housed in an 8-pin HSOIC package with PowerPAD™ technology, suitable for surface mount applications. It operates within a temperature range of -40°C to 125°C and is supplied on a large tape and reel with a standard package quantity of 2,500 units.
