Reference ground for the MOSFET and controller. VCC: Power supply input for the internal control circuitry.
To maintain high efficiency at medium-to-light loads, the IC "skips" resonance valleys, preventing the switching frequency from becoming too high. Str Z2756 Datasheet Pdf 11
Particularly power boards for LCD and Plasma TVs. Reference ground for the MOSFET and controller
The is a high-performance power IC manufactured by Sanken Electric Co., Ltd. (often distributed via Allegro MicroSystems ). It is specifically designed for use in quasi-resonant switching power supplies (SMPS), providing a combination of a controller chip and a power MOSFET in a single package. Core Technical Specifications Particularly power boards for LCD and Plasma TVs
Sets the timing for the soft start and overload protection delay.
Detects overcurrent and monitors the transformer's "bottom" voltage for resonant timing. Applications
The STR-Z2756 belongs to a family of regulators known for efficiency and low EMI noise. While it shares architecture with the more common STR-W and STR-X series, its specific ZIP-style package makes it a preferred choice for compact consumer electronics.
