TPS5450DDAG4 Description

Short technical summary and product information.

The Texas Instruments TPS5450DDAG4 is a high-output-current PWM converter designed for step-down applications. It operates with an input voltage range from 5.5V to 36V and can deliver up to 5A of continuous output current, with a peak capability of 6A. The device features a fixed switching frequency of 500kHz, which helps in reducing the size of external filter components.

 

This regulator is designed for efficiency, achieving greater than 90% with its integrated 110-mΩ MOSFET switch. The output voltage is adjustable down to 1.22V with an initial accuracy of 1.5%. It includes internal compensation to minimize external component count and features improved line regulation and transient response.

 

For system protection, the TPS5450DDAG4 incorporates overcurrent limiting, overvoltage protection, and thermal shutdown. It operates within a junction temperature range of -40°C to 125°C and is available in a small, thermally enhanced 8-pin SOIC PowerPAD™ package, suitable for surface mount applications.
