TPS54140ADRCR Description

Short technical summary and product information.

The Texas Instruments TPS54140ADRCR is a versatile 1.5A step-down DC DC switching regulator designed for efficient power management. It supports an input voltage range from 3.5V to 42V, making it suitable for a wide array of applications. The device integrates a high-side MOSFET with a low resistance of 200mΩ, contributing to high efficiency, especially at light loads with its Eco-mode™.

 

Key electrical characteristics include an adjustable output voltage, a switching frequency adjustable from 100kHz to 2.5MHz, and a low operating quiescent current of 116µA. The TPS54140ADRCR also features a shutdown current of 1.3µA and an internal voltage reference of 0.8V. It operates within a temperature range of -40°C to 150°C (TJ).

 

Packaged in a compact 10-VSON (3x3) or 10-VFDFN Exposed Pad, this surface-mount device is designed for ease of integration into various electronic designs. Its step-down (Buck) topology and adjustable output configuration provide flexibility for engineers designing power supplies and other power management circuits.
