The capacitor auto-discharge module presented in this article is simply a failsafe module that automatically discharges the buffer/filter capacitor in a power supply circuit when its input supply is ...

While passive precharge employs a power resistor to create an RC circuit that charges the capacitor asymptotically, active precharge can employ a switching converter with a buck topology that uses ...

Analogue Devices has combined switched capacitor and inductive buck conversion in the same topology to reduce the size of step-down dc-dc converters. Called LTC7821, this is “industry first hybrid ...

Professional condenser microphones require a 48-V supply to charge the internal capacitive transducer and power the internal buffer for the high-impedance transducer output. You can use a simple boost ...
