Schematic | A20112 Power Supply

Circuits using this IC can use smaller filters and capacitors, significantly lowering the total cost of the power unit. 2. Core Sections of an A20112 Schematic

Converts the incoming AC into a pulsing DC signal before PFC processing. DC-DC Conversion and Isolation a20112 power supply schematic

This is where the A20112 resides. It takes the rectified DC voltage and "corrects" the power factor, ensuring the current is in phase with the voltage. Circuits using this IC can use smaller filters
