The TPS51218 is a small D-Day ™ mode single buck controller with adaptive on-time. The device is suitable for low output voltage, high current, point-of-load (POL) power supplies with similar views on PC system rails and digital consumer products. A small pin-count package saves PCB space, while a new design designed for the EN pin and pre-set frequency selection reduces the design effort required. 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 high-side FETs that convert the input voltage range from 3 to 28 V and output voltages from 0.7 V to 2.
