TPS53219 Description
The TPS53219 is 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.
