The STR-Z2756 is engineered to optimize power delivery across varying load conditions through several specialized modes:
Reference ground for the MOSFET and controller. VCC: Power supply input for the internal control circuitry.
Minimizes stress on the internal MOSFET and external components during the initial power-up sequence. Pinout and Connection Guide Str Z2756 Datasheet Pdf 11
Particularly power boards for LCD and Plasma TVs.
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 The STR-Z2756 is engineered to optimize power delivery
Sets the timing for the soft start and overload protection delay.
Automatically lowers input power during very light or no-load conditions, helping products meet global energy-saving standards like Energy Star. Pinout and Connection Guide Particularly power boards for
Control boards that require reliable, efficient AC/DC conversion. Where to Find the Datasheet PDF STR-Z2756.pdf - IC Components
To maintain high efficiency at medium-to-light loads, the IC "skips" resonance valleys, preventing the switching frequency from becoming too high.
Typical configurations for this series include the following pin assignments (refer to the Sanken STR-Z2756 Official Documentation for exact pin numbers):
