To begin with, the power-supply integrated circuit (IC) is much more integrated ... a desired percentage of ripple current is less important in highly integrated, low-power step-down converters ...

The worst-case PSRR under worst-case conditions (low supply voltage and ... resulting -46 dB output ripple For additional details, questions, and/or comments, please contact us, the Georgia Tech ...

Many novel approaches to reduce ripple have been tried by manufacturers, including placing a filter on the output of the single-phase power supply, but with limited success. Other low-ripple power ...

Cascading a switching and linear voltage regulator produces a power supply ... are present at low input-to-output voltage conditions. In order to provide a low-voltage ripple supply to the core ...

A step-down SMPS (switched-mode power supply) efficiently converts unregulated ... you can use an SMPS to maintain high efficiency and a low-dropout regulator to reduce the output noise and ripple ...

The transformer isolates and steps down the AC voltage, the rectifier turns it into a rough DC, and the capacitors filter the DC to remove as much AC ripple as possible. In an audio power supply ...

The results imply that low ripple power supplies hold a distinct advantage over the conventional single-phase power supply because of their ability to apply more power to the precipitator field.

The new IC, which features ... manager at Power Integrations, said: "The combination of ZVS and GaN is power supply magic. Switching losses vanish, and we can leverage the low conduction losses ...
