TPS5450DDAR Description

Short technical summary and product information.

The TPS5450DDAR is a high-efficiency step-down DC-DC switching regulator designed to deliver up to 5 A of continuous output current with a 6 A peak capability. Operating with an input voltage range from 5.5 V to 36 V, this device provides an adjustable output voltage between 1.22 V and 31 V. The fixed 500 kHz switching frequency allows for the use of small external components while maintaining high efficiency greater than 90% across typical operating conditions.

 

Engineered for robust performance, the regulator incorporates a 110 mΩ integrated MOSFET switch to minimize conduction losses. It features voltage mode control with 1.5% initial accuracy and low quiescent current of 3 µA. Additional design protections include overcurrent protection and an enable pin for system power management. The shutdown supply current is limited to 18 µA, supporting energy-efficient standby modes.

 

Housed in an 8-pin HSOIC (DDA) surface-mount package measuring 4.9 mm by 6 mm, the TPS5450DDAR is optimized for space-constrained PCB layouts. It operates reliably across an extended temperature range from -40°C to 125°C. This component is suitable for industrial equipment, portable instruments, and battery-powered systems requiring efficient voltage regulation.
