TPS54233DR Description

Short technical summary and product information.

The TPS54233DR from Texas Instruments is a versatile step-down DC-DC converter designed for power management applications. It supports an input voltage range from 3.5V to 28V and can deliver up to 2A of continuous output current. The output voltage is adjustable down to 0.8V, providing flexibility for various design requirements.

 

This converter utilizes a current mode control for stable operation and features a fixed switching frequency of 300kHz. A key feature is its Eco-mode™ operation, which enhances efficiency at light loads through pulse skipping. The integrated 80 mΩ high-side MOSFET simplifies the external component count. Additional features include adjustable soft start, programmable UVLO, and protection mechanisms like cycle-by-cycle current limit and thermal shutdown.

 

The TPS54233DR is housed in an 8-SOIC package, measuring 4.9 mm x 6 mm, suitable for surface mount applications. Its operating temperature range is -40°C to 150°C (TJ).

 

Applications include consumer electronics such as set-top boxes and LCD displays, as well as industrial power supplies and car audio systems.
