Operates in QR switching mode to significantly reduce MOSFET switching losses and minimize electromagnetic interference (EMI).
: Available in standard space-saving formats, typically an 8-pin SOIC-8 package.
To ensure system reliability, the IC includes several safety features:
The AC mains supply passes through a fuse, an NTC thermistor (for inrush current limitation), an inductor-capacitor (LC) EMI filter network, and a full-bridge rectifier.
