TPS54394PWP Description

Short technical summary and product information.

The Texas Instruments TPS54394PWP is a highly efficient dual-channel synchronous step-down (buck) converter. It is designed for power management applications requiring a compact and versatile solution.

 

This device supports a wide input voltage range from 4.5V to 18V and can deliver up to 3A of output current per channel. The output voltage is adjustable, ranging from 0.76V to 7V, making it suitable for various voltage regulation needs. Key electrical features include a 700kHz switching frequency, integrated FETs with low on-resistance, and a D-CAP2 control mode for fast transient response and compatibility with ceramic output capacitors.

 

Designed for surface mounting, the TPS54394PWP is available in a 16-pin HTSSOP package. It operates within a temperature range of -40°C to 85°C. The integrated features such as Power Good, Soft Start, and Over-Current Limit enhance system reliability and simplify design.

 

Additional features include Auto-Skip Eco-mode for high efficiency at light loads, and protections like OCL/UVLO/TSD. The device's integrated FETs and loss-less current sensing contribute to its overall efficiency and performance.
