TPS40005DGQR Description

Short technical summary and product information.

The TPS40005DGQR from Texas Instruments is a fixed-frequency, voltage-mode synchronous buck controller. It is designed to drive N-channel MOSFETs for high-efficiency power conversion in low-voltage, non-isolated buck regulators. The controller features an operating input voltage range of 2.25V to 5.5V and can achieve output voltages as low as 0.7V.

 

Key features include an internal 0.7V reference with 1% accuracy, predictive gate drive technology for enhanced efficiency, and externally adjustable soft-start and overcurrent limit functions. The device supports both source-only current and source/sink current configurations, with versions available for starting into VOUT pre-bias conditions. It operates at a fixed frequency of 600kHz.

 

This controller is housed in a 10-lead MSOP PowerPad package, designed for higher performance. It includes essential protection features such as thermal shutdown and an internal bootstrap diode. The TPS40005DGQR is suitable for applications in networking equipment, telecom equipment, base stations, servers, DSP power, and power modules.
