TPS54329EDDA Description

Short technical summary and product information.

The Texas Instruments TPS54329EDDA is an integrated circuit designed for DC/DC power conversion. It functions as a synchronous step-down (buck) converter, capable of delivering up to 3A of output current.

 

Key electrical specifications include a wide input voltage range from 4.5V to 18V and an adjustable output voltage ranging from 0.76V to 7.0V. The device operates at a switching frequency of 650kHz, with integrated FETs for high efficiency. The high-side FET has a resistance of 100mΩ and the low-side FET has a resistance of 74mΩ. It also features a low quiescent current of typically 8µA and a maximum duty cycle of 85%.

 

This regulator is housed in an 8-pin SO PowerPad package, suitable for surface mount applications. The operating temperature range is -40°C to 85°C (TA). The package dimensions are approximately 4.9mm x 6mm.

 

The TPS54329EDDA incorporates features such as D-CAP2 mode for fast transient response and low output ripple, allowing the use of ceramic output capacitors. It also includes Auto-Skip Eco-mode for high efficiency at light loads, adjustable soft start, and cycle-by-cycle overcurrent protection.
