The Texas Instruments TPS54628 is an adaptive on-time D-CAP2 mode synchronous-buck converter designed for cost-effective, low-component count solutions. It supports a wide input voltage range of 4.5 V to 18 V and can regulate output voltages from 0.76 V to 5.5 V.
Key features include integrated FETs with low on-resistance (36 mΩ high-side, 28 mΩ low-side), enabling high efficiency. The device operates at a 650-kHz switching frequency and incorporates D-CAP2 mode for fast transient response without external compensation components. It also features Auto-Skip Eco-Mode for high efficiency at light loads and a shutdown current of less than 10 µA.
The TPS54628 is suitable for a wide range of low-voltage systems, including digital-TV power supplies, high-definition Blu-Ray disc players, networking home terminals, and digital set-top boxes. It is available in an 8-pin SO PowerPAD package designed for surface mounting.
This converter offers an adjustable soft-start time and prebiased soft start capability. It also includes cycle-by-cycle overcurrent limit protection and is optimized for lower duty-cycle applications.
