The TPS53219 is a small D-mode ™ single-control buck controller with adaptive turn-on time. The device is suitable for low output voltage, high current, PC system power rails and similar point of load fit (POL) power supplies in digital consumer products. The small package and minimal pin count save PCB space, while the power supply design is simplified by dedicated EN pins and pre-set frequency selection. Jump Mode Under light load conditions, the powerful gate driver and the R DS(ON) current sense of the low-side FET should support low loss and high efficiency over a wide load range, more than one. The converted input voltage (drain voltage of the high-side FET) ranges from 3 volts and 28 volts, and the output voltages range from 0.6 V and 5.
