Product Summary

The TPS51218DSCT is a small-sized single buck controller with adaptive on-time D-CAP mode. The device is suitable for low output voltage, high current, PC system power rail and similar point-of-load (POL) power supply in digital consumer products. A smallpackage with minimal pin-count saves space on the PCB, while a dedicated EN pin and pre-set frequency selections minimize design effort required for new designs. The applications of the TPS51218DSCT include Notebook Computers, I/O Supplies, System Power Supplies.
