The Texas Instruments TPS56428DDA is a synchronous step-down DC/DC switching regulator designed for efficient power conversion. It features a wide input voltage range of 4.5V to 18V and can deliver up to 4A of output current.
Key electrical specifications include a 650kHz switching frequency, D-CAP2™ control mode for fast transient response, and integrated FETs with low on-resistance (68 mΩ high-side, 37 mΩ low-side). The device offers features such as Enable, Light Load Efficiency, Power Good, and Soft Start. It also includes Advanced Eco-mode™ for high light load efficiency and a shutdown current of less than 10 µA.
The TPS56428DDA supports an adjustable output voltage ranging from 0.6V to 7.0V with 1% initial reference voltage accuracy. It has a fixed soft start time of 1.0ms and supports pre-bias output.
This regulator is available in an 8-SO PowerPad package and an 8-PowerSOIC package, both suitable for surface mounting. The operating temperature range is -40°C to 85°C.
