Description
The STR-S6703 is an original Sanken hybrid integrated circuit engineered specifically to meet the high integration and reliability demands of off-line quasi-resonant flyback power converters. This robust device cleanly integrates advanced primary control and proportional drive circuitry alongside a third-generation high-voltage bipolar switching transistor.
Key Features:
- Manufacturer: Sanken Electric Co., Ltd. (Originally distributed via Allegro MicroSystems)
- Package Type: ZIP-9 (9-pin Single/Zig-Zag In-line Power Package) with an integrated metal cooling fin for efficient heat dissipation.
- Topology: Quasi-Resonant Flyback (Delivers high operating efficiency, a low-power standby mode, and minimized electromagnetic interference/EMI).
- Maximum Output Power: Capable of managing power supply outputs up to 140W.
- Built-In Protections: Equipped with pulse-by-pulse over-current limiting, latched over-voltage protection, and internal thermal shutdown safeguards.
- Condition: Brand New / New Old Stock (NOS)
A vital replacement component frequently sought after by electronics repair technicians and arcade preservationists to service vintage TV chassis, retro CRT monitor power boards, and classic switch-mode power supplies (SMPS).
