STR-A6259H Datasheet | Allegro MicroSystems

BENEFITS provide high reliability of system design. 100 k Hz PWM with ±5% frequency jittering for EMI noise Cycle-by-cycle current limiting, undervoltage lockout with filtering cost reduction hysteresis, overvoltage protection, and thermal shutdown protect the power supply during the normal overload and fault conditions. .. Rugged 650 V avalanche-rated MOSFET: Overvoltage protection and thermal shutdown are latched after a - Simplified surge absorption short delay. The latch may be reset by cycling the input supply. Low start-up current and a low-power standby mode selected - No VDSS derating required from the secondary circuit pletes a prehensive suite of Low RDS(on) : 6 Ω maximum Features . Auto-burst mode for stand-by operation or light loads; less It is provided in an 8-pin mini-DIP plastic package with pin 6 removed. The leadframe plating is pure Sb, and the package transformer audible noise plies with Ro HS.
