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): Str Z2756 Datasheet Pdf 11
Connection to the primary side of the transformer. To maintain high efficiency at medium-to-light loads, the
Detects overcurrent and monitors the transformer's "bottom" voltage for resonant timing. Applications Applications The STR-Z2756 belongs to a family of
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.
