Description
The STR-S5707 is an original, high-reliability hybrid integrated circuit developed by Sanken. It is specifically engineered for use in off-line quasi-resonant flyback power converters with indirect feedback. This device incorporates an advanced primary control and proportional drive circuit paired with a third-generation high-voltage bipolar switching transistor.
Key Features:
- Manufacturer: Sanken Electric Co., Ltd. (Originally distributed via Allegro MicroSystems)
- Package Type: Over-molded SIP-9 (9-pin Single In-line Power Package) with an integrated isolated heat spreader.
- Topology: Quasi-Resonant Flyback (Delivers high efficiency and low electromagnetic interference/EMI).
- Built-In Protections: Features pulse-by-pulse over-current protection, latched over-voltage protection, thermal shutdown safeguards, and internal under-voltage lockout (UVLO) with hysteresis.
- Condition: Brand New / New Old Stock (NOS)
A vital replacement component heavily used for servicing vintage cathode-ray tube (CRT) television chassis, arcade display monitors, and legacy switch-mode power supplies (SMPS) requiring an exact-match semiconductor.
