Description
The STR-S5708 is an original Sanken hybrid integrated circuit engineered specifically to deliver stable power management in off-line quasi-resonant flyback converters featuring indirect feedback. This high-reliability device integrates a primary control and proportional drive circuit with a high-performance, third-generation high-voltage bipolar switching transistor.
Key Features:
- Manufacturer: Sanken Electric Co., Ltd. (Distributed via Allegro MicroSystems)
- Package Type: Over-molded SIP-9 (9-pin Single In-line Power Package) with an integral isolated heat spreader.
- Topology: Quasi-Resonant Flyback Switching Regulator (Low EMI and High Efficiency)
- Advanced Built-In Safety: Pulse-by-pulse over-current protection, latched over-voltage protection, internal under-voltage lockout (UVLO) with hysteresis, and thermal shutdown protection.
- Condition: Brand New / New Old Stock (NOS)
Widely relied upon for repairing legacy cathode-ray tube (CRT) television chassis, high-performance display monitors, and vintage power supply units requiring exact-match semiconductor replacements.
