TPS40000DGQR Description

Short technical summary and product information.

The TPS40000DGQR from Texas Instruments is a fixed-frequency, voltage-mode control IC for low-voltage, non-isolated synchronous buck regulators. It drives N-channel MOSFETs for both the primary buck switch and the synchronous rectifier, enabling high-efficiency power conversion.

 

Key features include an operating input voltage range of 2.25V to 5.5V and the ability to achieve output voltages as low as 0.7V. The device incorporates a 1% internal 0.7V reference and offers externally adjustable soft-start and overcurrent limit functions. It utilizes TI's proprietary Predictive Gate Drive technology to minimize synchronous rectifier losses, enhancing overall efficiency.

 

This controller is suitable for applications requiring efficient power conversion, such as networking equipment, telecom equipment, base stations, servers, DSP power, and power modules. The TPS40000DGQR 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 controller operates at a fixed frequency of 300kHz and features synchronous rectification.
