TPS40040DRBR Description

Short technical summary and product information.

The TPS40040DRBR from Texas Instruments is a low pin count, synchronous buck DC-to-DC controller. It is designed to operate within an input voltage range of 2.25V to 5.5V, making it suitable for various power supply applications.

 

Key electrical specifications include a maximum output current capability of 15A and a fixed switching frequency of 300kHz. The controller supports a wide output voltage range from 0.6V up to 90% of VIN. It features voltage mode control, an enable pin for control, and synchronous rectification for improved efficiency.

 

Packaged in an 8-SON (3x3) surface-mount package, the TPS40040DRBR is designed for applications such as point-of-load power, telecommunications, and DC to DC modules. The operating temperature range is -40°C to 125°C (TJ).

 

Additional features include prebias startup, adaptive anti-cross conduction gate drive, and selectable short circuit protection levels. Thermal shutdown protection is also included at 145°C.
