The TPS53219A device is a small-sized single buck controller with adaptive ON-time D-CAP mode control. The device is suitable for low output voltage, high current, PC system power rail and similar point-of-load (POL) power supplies in digital consumer products. The small package and minimal pin-count save space on the PCB, while the dedicated EN pin and pre-set frequency selections simplify the power supply design. The skip mode at light load conditions, strong gate drivers, and low-side FET RDS(on) current sensing supports low-loss and high efficiency, over a broad load range. The conversion input voltage (high-side FET drain voltage) range is between 4.5 V and 25 V, and the output voltage range is between 0.6 V and 5.5 V. The TPS53219A is available in a 16-pin, QFN package specified from –40°C to +85°C.
