DESCRIPTION
The ETA8003x is an ETA SR’s family product which is a high performance and highly integrated secondary side synchronous rectifier in switch mode power supply system. It integrates various low voltage drop N-channel MOSFET to replace the output rectifier diode in a flyback topology. This can reduce heat dissipation, improve system efficiency, and simplify thermal design. It can effectively help power system meet the latest DOE2.0 standard average efficiency requirement. Very low quiescent current in standby mode ensures lower system standby power.
The ETA8003x is suitable for flyback converter operating in continuous conduction mode (CCM), discontinuous conduction mode (DCM), and quasiresonant mode. Especially for CCM, to guarantee system reliability, Patented Gate voltage adjustment technology and Fast shutdown judgment methods are used in SR turn-off control.
The ETA8003x can support wide range of system output voltage 5-20V offline AC/DC flyback converter with universal AC inputs, such as PD/QC adaptor e.g. It is suitable for fast charging power solutions within 45W.
APPLICATIONS
■ Universal AC-DC adaptors
■ USB QC/PD Quick Chargers/Adaptors
■ Flyback Power Supplies with Variable Output Voltage
■ High Output Current Flybacks
■ High Efficiency Flybacks
