TPS54528DDA Description

Short technical summary and product information.

The Texas Instruments TPS54528DDA is an adaptive on-time D-CAP2 mode synchronous buck converter. It is designed for power management applications, offering a wide input voltage range from 4.5V to 18V and an adjustable output voltage range of 0.76V to 6V.

 

Key electrical specifications include a maximum output current of 5A and a switching frequency of 650kHz. The device features integrated FETs with low on-resistance (65 mΩ high side, 36 mΩ low side) for high efficiency, especially at lower duty cycles. It also includes features like Auto-Skip Eco-mode for improved light-load efficiency and a quiescent current of typically 0.0009A.

 

The TPS54528DDA is housed in an 8-SO PowerPad package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C (TA). The D-CAP2 mode enables fast transient response and low output ripple, allowing the use of ceramic output capacitors.

 

This converter is suitable for various power supply designs requiring efficient voltage regulation. Its adjustable output and integrated components simplify design and reduce board space.
