Switching-Regulator Insights—Achieving Longer Battery Life in DSP Systems

Step-down dc-to-dc switching regulators efficiently derive a low voltage from a higher voltage, maintaining a constant output despite variations in supply voltage or load current. This article describes an architecture that provides good regulation, high efficiency, and fast response, showing both fixed-voltage operation and a resistor-programmable circuit that provides dynamic voltage scaling in DSP applications.

Output of regulator consisted large spectrum of harmonics (depend from switch frequency).Somethimes are necessity to be placed a small caps in out with value 68 - 220nF.
