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.
The R2A20112 is designed by Renesas to improve efficiency and reduce noise in power supply designs. Its schematic footprint typically includes:
Specifically models like the HSP400-5S01.
A critical magnetic component that stores energy.
By sensing zero current, the IC reduces switching losses in the boost diode, leading to higher overall efficiency.
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
