TPS54328DRCR Description

Short technical summary and product information.

The TPS54328DRCR from Texas Instruments is a 3A synchronous step-down (buck) converter designed for power management applications. It operates with an input voltage range of 4.5V to 18V and provides an adjustable output voltage from 0.76V to 7V.

 

Key electrical specifications include a maximum output current of 3A, a switching frequency of 700kHz, and a typical quiescent current of 0.0008A. The device integrates high-efficiency FETs with low on-resistance (100 mΩ high-side, 70 mΩ low-side) and features Auto-Skip Eco-Mode for improved efficiency at light loads. It also includes an adjustable soft-start function and cycle-by-cycle overcurrent protection.

 

Packaged in a 10-VSON (3x3) footprint, the TPS54328DRCR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. The D-CAP2 mode enables fast transient response and allows the use of ceramic output capacitors, contributing to a low output ripple.

 

This converter is well-suited for various power supply designs requiring efficient voltage regulation within the specified input and output ranges.
