A20112 Power Supply Schematic Updated (2026)

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

Commonly delivers split rail voltages (e.g., +15V, -15V for operational amplifiers) or standard digital logic lines (+5V). a20112 power supply schematic

(Zero Current Detection): Detects when the inductor current reaches zero, signaling the IC to turn the MOSFET back on. This ensures Critical Conduction Mode. 3. Detailed Circuit Operation Sequence Converts the incoming AC into a pulsing DC
