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 efficiency.The RT7220E supports a wide output voltage range from 5V to 48V, and a HV LDO is built-in for the MOSFET gate driver at low output voltage. When used with the AHB controller RT7795, the double pulses function can be enabled to optimize efficiency at heavy load/low output voltage.Furthermore, the RT7220E provides green mode operation under light load conditions, reducing operation current to below 160μA.The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 105°C.
