The TPS54428DDAR from Texas Instruments 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 up to 4A of output current.
This converter utilizes the D-CAP2™ control mode, enabling fast transient response and low output ripple, which allows for the use of ceramic output capacitors. It also incorporates Eco-mode™ for high efficiency at light loads and an auto-skip mode. The integrated FETs offer high efficiency with low on-resistance: 70 mΩ for the high-side and 53 mΩ for the low-side.
Key electrical specifications include an adjustable output voltage range from 0.76V to 7.0V and a switching frequency of 650kHz. The device operates within a temperature range of -40°C to 85°C.
The TPS54428DDAR is available in an 8-SO PowerPad package, suitable for surface mount applications. It offers features such as adjustable soft-start, cycle-by-cycle overcurrent limit, and a low shutdown current of less than 10 µA.
