Key Featrues
D-CAP2™ Mode Control: This feature enables fast transient response without the need for external compensation components, improving system stability and reducing design complexity. It is particularly beneficial in applications requiring rapid load changes, such as point-of-load (POL) power supplies.
Auto-Skip Eco-Mode™: At light loads, the TPS54628 automatically switches to Eco-Mode, significantly reducing power consumption and enhancing efficiency. This makes it ideal for battery-powered or energy-sensitive applications where minimizing standby current is critical.
Wide Input Voltage Range (4.5 V to 18 V): The device supports a broad input voltage range, allowing it to be used in diverse applications, including industrial, automotive, and consumer electronics. This versatility simplifies power supply design across multiple use cases.
Integrated FETs with Low On-Resistance: The high-side and low-side FETs have low on-resistance (36 mΩ and 28 mΩ, respectively), reducing conduction losses and improving overall efficiency, especially in lower duty-cycle applications.
Adjustable Soft Start and Prebiased Startup: The adjustable soft-start feature minimizes inrush current during startup, while the prebiased startup capability ensures safe operation in systems where the output voltage is already present. This enhances reliability and protects sensitive components.
