LM2630, Synchronous Step-Down Power Supply Controller

The LM2630 controller provides all the active functions for step-down (buck) switching converters. These dc-to-dc converters provide core CPU power in battery-operated systems. High efficiency is achieved by using synchronous rectification and pulse-skipping mode operation at light load. Inexpensive.
