TPS40004DGQR Description

Short technical summary and product information.

The TPS40004DGQR from Texas Instruments is a controller for low-voltage, non-isolated synchronous buck regulators. It is designed to drive 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 an internal 0.7V reference. The device operates at a fixed frequency of 300kHz and features externally adjustable soft-start and overcurrent limit controls. It supports synchronous rectification for improved efficiency.

 

This controller is housed in a 10-lead MSOP PowerPad package, designed for higher performance. The operating temperature range is -40°C to 85°C (TA). Applications include networking equipment, telecom equipment, base stations, servers, DSP power, and power modules.

 

Mounting is via surface mount technology. The package is a 10-HVSSOP, also described as 10-PowerTFSOP or 10-MSOP with specific dimensions.
