The Texas Instruments TPS54228 is a synchronous step-down DC/DC converter designed for power management applications. It features a wide input voltage range of 4.5V to 18V and can deliver an output current of up to 2A, with an adjustable output voltage ranging from 0.76V to 7V.
This device utilizes the D-CAP2 control mode, enabling fast transient response and low output ripple, making it suitable for use with ceramic output capacitors. Key electrical specifications include a switching frequency of 700 kHz, integrated FETs with low on-resistance (155 mΩ high-side, 108 mΩ low-side), and a typical quiescent current of 0.0008A. It also offers features like adjustable soft-start and cycle-by-cycle overcurrent protection.
The TPS54228 operates within a temperature range of -40°C to 85°C. It is available in multiple package options including HSOIC (DDA), VSON (DRC), and SOIC (D), with package sizes measuring 29.4 mm² (4.9 mm × 6 mm) and 9 mm² (3 mm × 3 mm).
Additional features include Auto-Skip Eco-Mode for high efficiency at light loads and a shutdown current of less than 10 µA. The device supports adjustable soft-start and prebiased soft start functionalities.
