    2. 2 Current Mode Buck Converter LM3075 from National Semiconductor The LM3075 is a current mode control, synchronous buck controller IC. Current mode control assures excellent line and load regulation and a wide loop bandwidth for fast response to load transients. Other features cycle by cycle current limit, 1.24V?2% reference Application area: automotive power supplies and distributed power systems

    3. 3 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 200kHz or 300kHz from an internal clock.
