WebIn the equations (1) and (2), the output current is used as the . This is the average current of the inductor. As shown in the lower part of Figure 2, greater losses are generated in the actual ramp waveforms. If the current waveform is sharper (peak current is higher), the effective current is obtained by integrating the square of the differential Webtional voltage feedback loop and a unique current feedback loop to operate as a constant-current, constant-voltage source. This fixed frequency, current mode switcher oper-ates from a wide input voltage range of 1.6V to 18V, and the high switching frequency of 1.4MHz permits the use of tiny, low profile inductors and capacitors.
