The LM3075 is a current mode control, synchronous buck controller IC. Use of synchronous rectification and pulse- skipping 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 switching frequency can be selected as either 200 kHz or 300 kHz from an internal clock. The LM3075 is available with an adjustable output in a TSSOP-20 package.
