Switch-mode power supplies are used in electronic circuits to increase (step up) or reduce (step down) voltage levels in the most efficient manner possible. Compared to linear voltage regulators, ...

Step-down converters’ switch-node voltage waveform defines the electromagnetic compatibility (EMC) behavior for automotive CISPR 25 Class 5 measurements. The ringing frequency in the switch-node ...

Thanks to a pseudo-fixed-frequency architecture, the AAT1130, a 500-mA monolithic step-down converter, offers transient response that’s said to be at least twice as fast as a traditional 500-mA, 2-MHz ...
