LM3075 Synchronous Current Mode Buck Controller

The LM3075 is a current mode control, synchronous buck controller IC. Use of synchronous rectification and pulseskipping operation at light load achieves high efficiency over a wide load range. Fixed frequency operation can be obtained by disabling the pulse-skipping mode. Current mode control assur.
