TPS40000DGQG4 Description

Short technical summary and product information.

The TPS40000DGQG4 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 features include an operating input voltage range of 2.25V to 5.5V and an output voltage as low as 0.7V. It incorporates a 1% internal 0.7V reference and predictive gate drive technology for N-channel MOSFETs, enhancing efficiency. The device also offers externally adjustable soft-start and overcurrent limit functions.

 

This controller operates at a fixed frequency of 300kHz and supports synchronous rectification. It is available in a 10-lead MSOP PowerPad package, designed for higher performance. The TPS40000DGQG4 includes thermal shutdown and an internal bootstrap diode.

 

Applications for this controller include networking equipment, telecom equipment, base stations, servers, DSP power, and power modules.
