Reduces electromagnetic interference (EMI) and switching losses by ensuring the MOSFET switches at the lowest possible voltage (soft switching).
Particularly power boards for LCD and Plasma TVs. Str Z2756 Datasheet Pdf 11
Detects overcurrent and monitors the transformer's "bottom" voltage for resonant timing. Applications the IC "skips" resonance valleys

To maintain high efficiency at medium-to-light loads, the IC "skips" resonance valleys, preventing the switching frequency from becoming too high.
