LM3075 High Efficiency, Synchronous Current Mode Buck Controller
General Description
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 assures excellent line and load regulation and a wide loop bandwidth for fast response to load transients. .. Current mode control can be achieved by either sensing across the high side NFET or a sense resistor. The...
