TPS54040DGQR Description

Short technical summary and product information.

The Texas Instruments TPS54040DGQR is a versatile step-down DC/DC converter designed for power management applications. It features a wide input voltage range from 3.5V to 42V and can deliver up to 500mA of output current.

 

This device utilizes current mode control for simple external compensation and flexible component selection. It offers high efficiency at light loads through its Pulse Skipping Eco-Mode, reducing quiescent current to 116µA. The switching frequency can be adjusted from 100kHz to 2.5MHz and can synchronize to an external clock.

 

The TPS54040DGQR includes features such as adjustable slow start/sequencing, UV and OV power good output, and adjustable undervoltage lockout (UVLO) with hysteresis. It has an integrated 0.8V internal voltage reference and a 200mΩ high-side MOSFET.

 

Packaged in a 10-pin HVSSOP or 10-MSOP (PowerPAD) package, this regulator is suitable for surface mount applications. The operating temperature range is -40°C to 150°C (TJ).
