The TPS53219 is a small D-Day ™ mode single-control buck controller that adapts to turn-on time. The device is suitable for low output voltage, high current, PC system power rails and similar point load fit (POL) power supplies in digital consumer products. The small package and minimum pin count save PCB space, while designing for EN pins and preset frequency selection simplifies power supply design. Skip mode with powerful gate drivers and low-side FETs at light loads_targetR_DS（ON）Current sensing supports low losses and high efficiency over a wide load range, over one. The converted input voltage (drain voltage of the high-side FET) ranges from 3 volts and 28 volts, and the output voltage ranges from 0.6 V and 5.
