Product Summary

The Z1014AI is a high efficiency, simple to use, 5A buck regulator. The Z1014AI works from a 4.5V to 16V input voltage range, and provides up to 5A of continuous output current with an output voltage adjustable down to 0.8V. The Z1014AI comes in SO-8 and DFN-8 packages and is rated over a -40°C to +85°C ambient temperature range. Applications are (1)Point of load DC/DC conversion; (2)PCIe graphics cards; (3)Set top boxes; (4)DVD drives and HDD; (5)LCD panels; (6)Cable modems; (7)Telecom/networking/datacom equipment.
