TPS54228DR Description

Short technical summary and product information.

The Texas Instruments TPS54228DR is an adaptive on-time D-CAP2 mode synchronous buck converter. It is designed for cost-effective, low component count power bus regulation.

 

Key electrical specifications include an input voltage range of 4.5V to 18V and an adjustable output voltage range from 0.76V to 7V. It can deliver up to 2A of output current and operates at a switching frequency of 700kHz. The device features integrated FETs with low on-resistance (155 mΩ high-side, 108 mΩ low-side) and a low shutdown current of less than 10 μA.

 

This converter supports D-CAP2 mode for fast transient response and allows the use of ceramic output capacitors. It also incorporates Eco-mode™ for high efficiency at light loads and an adjustable soft-start circuit. The operating temperature range is -40°C to 85°C.

 

The TPS54228DR is available in an 8-SOIC package and is suitable for surface mount applications. Its design is optimized for lower duty cycle applications.
