The TPS54328DDAR is an Integrated Circuit (IC) component manufactured by Texas Instruments. It is a synchronous step-down converter with a wide input voltage range, designed for use in various applications such as consumer electronics, industrial equipment, and telecommunications.
One of the key features of the TPS54328DDAR is its ability to operate over a wide input voltage range of 3.6V to 36V. This makes it suitable for both single-cell and multi-cell battery-powered systems or any other application where the input voltage can vary significantly.
The IC operates as a step-down converter, which means it steps down the input voltage to a lower, regulated output voltage. It can provide an adjustable output voltage range from 0.76V to 20V, making it versatile for different applications. The adjustable output voltage is set using external resistors.
The TPS54328DDAR offers a high-efficiency conversion due to its synchronous rectification architecture. It achieves this efficiency by using a pair of MOSFET switches instead of diodes, reducing power losses during the conversion process. This makes it suitable for applications with strict power efficiency requirements, such as battery-powered devices where longer battery life is desired.
To ensure stable and reliable operation, the IC provides various protection features. It includes over-temperature protection that shuts down the converter in case of excessive heat, preventing damage to the IC
