TPS40001DGQR Description

Short technical summary and product information.

The TPS40001DGQR from Texas Instruments is a fixed-frequency, voltage-mode control IC designed for non-isolated synchronous buck regulators. It drives N-channel MOSFETs for high-efficiency power conversion, featuring TI's proprietary Predictive Gate Drive technology to minimize switching losses.

 

Key electrical specifications include an operating input voltage range of 2.25V to 5.5V and an output voltage capability as low as 0.7V. The device operates at a switching frequency of 300kHz and includes features such as adjustable soft-start and overcurrent limit. It also incorporates an internal 0.7V reference with 1% accuracy.

 

This controller is suitable for applications requiring efficient power conversion, such as networking equipment, telecom equipment, base stations, servers, DSP power supplies, and power modules. The TPS40001DGQR is housed in a 10-lead MSOP PowerPad package, designed for higher performance and thermal management.

 

Mounting is via surface mount technology. The operating temperature range is -40°C to 85°C (TA). The package is a 10-HVSSOP, with an alternative description of 10-PowerTFSOP, 10-MSOP (0.118", 3.00mm Width).
