The Texas Instruments TPS56428DDAR is a versatile synchronous step-down (buck) converter designed for efficient power management. It operates with an input voltage range from 4.5V to 18V and can deliver up to 4A of output current. The device features a fixed switching frequency of 650kHz, supporting D-CAP2 mode for fast transient response and ceramic capacitor compatibility.
Key electrical characteristics include adjustable output voltage from 0.6V to 5.5V, low quiescent current, and a shutdown current of less than 10µA. The integrated FETs are optimized for efficiency, with low-side and high-side resistances specified. It also includes features like soft start, power good output, and cycle-by-cycle overcurrent protection.
Packaged in an 8-SO PowerPad (8-PowerSOIC) surface-mount package, the TPS56428DDAR is suitable for various applications requiring compact and efficient power conversion. Its operating temperature range is -40°C to 85°C (TA), making it robust for different environmental conditions.
