RT7220E Description
The RT7220E is a Synchronous Rectifier (SR) controller for Asymmetrical Half-Bridge (AHB) converters operating in Critical Conduction Mode (CRM), Cycle Skipping Mode (CSM), and Burst Mode (BM). The RT7220E detects the drain voltage of the MOSFET to control the on/off state of the SR gate. This functionality is intended to minimize turn-off dead-time and deliver sine-wave energy through the SR gate pulses, enhancing...
