LV14340 Description

Short technical summary and product information.

The LV14340 from Texas Instruments is a versatile step-down (buck) converter designed for a wide input voltage range of 4V to 40V, making it suitable for various industrial and automotive applications. It can deliver a continuous output current of up to 3.5A.

 

This device features an adjustable switching frequency, allowing users to optimize for efficiency or component size, ranging from 200kHz to 2MHz. It incorporates current mode control and internal compensation, simplifying the design process by minimizing the need for external components. The integrated high-side MOSFET has a low on-resistance of 100mΩ.

 

Key features include a precision enable input for simplified control and system power sequencing, and a low shutdown current of 1µA. The LV14340 also includes built-in protection mechanisms such as cycle-by-cycle current limit, thermal shutdown, and output overvoltage protection.

 

The LV14340 is available in an 8-pin HSOIC package with an exposed pad (PowerPAD™) for enhanced thermal performance. The package dimensions are 4.9mm x 6mm.
