TPS54140DGQR Description

Short technical summary and product information.

The TPS54140DGQR from Texas Instruments is a versatile 1.5A step-down (buck) DC/DC converter designed for a broad input voltage range of 3.5V to 42V. This device integrates a high-side MOSFET and utilizes current mode control for simple external compensation and flexible component selection.

 

Key electrical specifications include an adjustable output voltage with a minimum of 0.8V and a maximum of 39V, and a wide switching frequency range from 100kHz to 2.5MHz. It boasts a low operating quiescent current of 116μA and a shutdown current of 1.3μA, contributing to high efficiency, especially at light loads with its Eco-Mode™ feature. The integrated 200mΩ high-side MOSFET enhances efficiency and reduces component count.

 

Packaged in a 10-pin MSOP (PowerPAD™) with a Surface Mount type, the TPS54140DGQR is suitable for various applications including 12V and 24V industrial and commercial low power systems, and aftermarket automotive accessories. Its operating temperature range is -40°C to 150°C (TJ). Features like adjustable slow start, power good output, and adjustable UVLO enhance design flexibility.
