Control boards that require reliable, efficient AC/DC conversion. Where to Find the Datasheet PDF STR-Z2756.pdf - IC Components
Reduces electromagnetic interference (EMI) and switching losses by ensuring the MOSFET switches at the lowest possible voltage (soft switching). Str Z2756 Datasheet Pdf 11
To maintain high efficiency at medium-to-light loads, the IC "skips" resonance valleys, preventing the switching frequency from becoming too high. Control boards that require reliable
Minimizes stress on the internal MOSFET and external components during the initial power-up sequence. Pinout and Connection Guide the IC "skips" resonance valleys
Detects overcurrent and monitors the transformer's "bottom" voltage for resonant timing. Applications
Reference ground for the MOSFET and controller. VCC: Power supply input for the internal control circuitry.
Receives the feedback signal (often via an optocoupler) for constant voltage regulation.
