TPS40002DGQR Description

Short technical summary and product information.

The Texas Instruments TPS40002DGQR is a fixed-frequency, voltage-mode control DC/DC switching controller. It is designed for low-voltage, non-isolated synchronous buck regulators, driving N-channel MOSFETs for high-efficiency power conversion. The device features an operating input voltage range of 2.25V to 5.5V and can provide output voltages as low as 0.7V, with an internal 0.7V reference.

 

Key features include predictive gate drive technology for higher efficiency, externally adjustable soft-start, and overcurrent limit. It supports source-only current or source/sink current versions and can start into VOUT pre-bias. The controller operates at a fixed frequency of 600kHz and includes thermal shutdown and an internal bootstrap diode.

 

This controller is suitable for applications such as networking equipment, telecom equipment, base stations, servers, and DSP power. It is housed in a 10-lead MSOP PowerPad package for enhanced performance, with an operating temperature range of -40°C to 85°C.

 

The TPS40002DGQR is available in a 10-HVSSOP package and is surface-mount compatible. It offers a maximum duty cycle of 93% and a single output phase.
