Optimization of Single, Double and Triple Voltage Dc to Dc Step down Voltage Regulators

Switching voltage regulators are frequently used as power foundation of the IC circuit loads. To guarantee the voltage permanence switching type voltage regulators uses LC low pass filter in output terminal. Size of inductor and cost are two of main concerns in circuit designing, changing the input parameters like inductance capacitance and switching frequency in order to observe changes in output voltage has been added with simulation graphs .These parameters and there equations should be well understood before scheming step down converters. Simulation procedures in LTSPICE are also added in this paper. This paper presents an optimization of integrated circuit based step down dc - dc switching voltage regulators.
