Most dc-dc converters require a soft-start circuit to limit the in-rush current at startup. Although a smooth soft start is required for systems with power-on reset (POR), this is difficult to ...

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 ...

I intially purchased the $30 Sonic T amp just to hear what all the buzz on a few forums and internet review sites was all about. My intial impression of the cheapo plastic boxed, “AAA” battery powered ...

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 ...

The process of designing traditional fixed-supplypower amplifiers has been well-establishedfor many years. Well-definedmetrics for performance assessment exist,and the amplifier designer’s job is to ...
