TPS54040DGQ Description

Short technical summary and product information.

The Texas Instruments TPS54040DGQ is a versatile step-down DC/DC converter designed for power management applications. It accepts an input voltage range from 3.5V to 42V and can deliver up to 0.5A of output current.

 

This device utilizes current mode control for simple external compensation and flexible component selection. It features a high-side MOSFET with a low 200mΩ resistance. The converter operates with a switching frequency adjustable from 100kHz to 2.5MHz, allowing for optimization of component size and efficiency.

 

Key features include a low operating quiescent current of 116µA and a shutdown current of 1.3µA, contributing to high efficiency at light loads with its Eco-Mode™ pulse skipping capability. It also offers an adjustable slow start/sequencing feature, UV and OV power good output, and adjustable UVLO voltage with hysteresis. The internal voltage reference is set at 0.8V.

 

The TPS54040DGQ is supplied in a 10-HVSSOP package, suitable for surface mount applications. The operating temperature range is -40°C to 150°C (TJ).
