TPS54326RGTR Description

Short technical summary and product information.

The TPS54326RGTR from Texas Instruments is a 3A synchronous step-down (buck) converter designed for power management applications. It accepts an input voltage ranging from 4.5V to 18V and can provide an adjustable output voltage between 0.76V and 5.5V. This device utilizes the D-CAP2 control mode, which enables fast transient response and allows for the use of ceramic output capacitors.

 

Key electrical characteristics include a maximum output current of 3A and a switching frequency of 700kHz. The integrated FETs have low resistance (120 mΩ high side, 70 mΩ low side) contributing to high efficiency. It also features Eco-Mode for improved efficiency at light loads and a shutdown current of less than 10 µA. The operating temperature range is -40°C to 85°C.

 

Packaged in a 16-VQFN (3x3) with an exposed pad, the TPS54326RGTR is designed for surface mount applications. Its features such as adjustable soft-start, power good output, and cycle-by-cycle overcurrent limit make it suitable for a wide range of low-voltage systems including digital TVs, networking equipment, and set-top boxes.
