TPS54494PWPR Description

Short technical summary and product information.

The TPS54494PWPR from Texas Instruments is a versatile dual-channel synchronous step-down (buck) switching regulator. It is designed for efficient power conversion with integrated FETs.

 

Key electrical specifications include a maximum output current of 4A for channel 1 and 2A for channel 2. The device operates over a wide input voltage range of 4.5V to 18V, with an adjustable output voltage ranging from 0.76V to 7V. It features a switching frequency of 700kHz and a typical quiescent current of 1.2mA. The integrated FETs have a low-side resistance of 60 mΩ and a high-side resistance of 90 mΩ.

 

This regulator utilizes the D-CAP2 control mode, offering fast transient response and eliminating the need for external loop compensation components. It is compatible with ceramic output capacitors. The operating temperature range is -40°C to 85°C.

 

The TPS54494PWPR is available in a 16-pin HTSSOP package, suitable for surface mount applications. It includes features like Power Good, soft-start, and over-current protection.
