TPS54494PWP Description

Short technical summary and product information.

The TPS54494PWP from Texas Instruments is a dual-channel synchronous step-down switching regulator designed for efficient power conversion. It supports a wide input voltage range from 4.5V to 18V and provides adjustable output voltages from 0.76V to 7V.

 

This device features integrated FETs with low on-resistance (90 mΩ high side, 60 mΩ low side) and supports high output currents of up to 4A for channel 1 and 2A for channel 2. The regulator operates at a switching frequency of 700kHz and utilizes the D-CAP2 control mode for fast transient response and compatibility with ceramic output capacitors.

 

Packaged in a 16-HTSSOP, the TPS54494PWP is suitable for surface mount applications. It includes features such as soft-start, power good indication, and over-current protection, making it a versatile component for various power management designs.
