Switching power supply whose output voltage is appreciably lower than its input voltage has an interesting property: the current drawn by it is smaller than its output current. However, the input ...

The two power supply circuits are presented to illustrate the soft start procedure using LM317 and L200 integrated circuits where each reaches the desired output of 15 V gradually for a period of 5 ...

Obviously, long battery life is a significant design goal for portable devices. Much effort is put into maximizing the efficiencies of the DC-DC converters in these products since that clearly extends ...

This article addresses a characteristic found in many battery-powered products. When power to a circuit is first applied, high peak currents are encountered during the time taken to establish stable ...
