The IC drives the Power MOSFET (Q₁) on and off at a high frequency (often ≈ 84 kHz).

Adopts CRM for high efficiency and low switching noise via zero current switching. Interleaving Control:

(Feedback): Monitors the output voltage. If the output voltage goes too high, the A20112 reduces its duty cycle. ISENcap I sub cap S cap E cap N end-sub
