TPS54527DDA Description

Short technical summary and product information.

The Texas Instruments TPS54527DDA is a synchronous step-down (buck) converter designed for efficient power management. It features a wide input voltage range of 4.5V to 18V and can deliver a maximum output current of 5A. The output voltage is adjustable, ranging from 0.76V to 6V, making it versatile for various applications.

 

This converter operates at a switching frequency of 650kHz, contributing to its compact design and efficient operation. It includes integrated FETs with low resistance (65 mΩ high side, 36 mΩ low side) and utilizes the D-CAP2 mode for fast transient response and low output ripple. The operating temperature range is -40°C to 85°C.

 

The TPS54527DDA is housed in an 8-SO PowerPad package, suitable for surface mounting. Its design aims to provide a cost-effective, low component count solution for power bus regulation in end equipment.
