TPS40009DGQRG4 Description

Short technical summary and product information.

The TPS40009DGQRG4 from Texas Instruments is a controller for low-voltage, non-isolated synchronous buck regulators. It drives N-channel MOSFETs for both the primary buck switch and the synchronous rectifier switch, enabling high-efficiency power conversion.

 

Key electrical specifications include an operating input voltage range of 2.25V to 5.5V and a fixed switching frequency of 600kHz. The controller features an internal 0.7V reference with 1% accuracy and supports output voltages as low as 0.7V. Control features include adjustable soft-start and overcurrent limit.

 

This device is housed in a 10-lead HVSSOP package and is designed for surface mount applications. The operating temperature range is -40°C to 85°C. It is suitable for applications in networking equipment, telecom equipment, base stations, servers, and DSP power modules.
