Микросхема STRA6259H (маркировка A6259H)
STRA6259H - Universal-Input 13W 100kHz Flyback Switching Regulators, DIP-8
FEATURES
100 kHz PWM with ±5% frequency jittering for EMI noise filtering cost reduction
Rugged 650 V avalanche-rated MOSFET:
Simplified surge absorption
No VDSS derating required
Low RDS(on) : 6 Ω maximum
Auto-burst mode for stand-by operation or light loads; less transformer audible noise
Built-in leading edge blanking
Soft start and low start-up current; start-up circuit disabled i operation
Auto-burst stand-by (intermittent operation) input power < 0.1 W at no load
Built-in constant-voltage/constant current (CV/CC) Multiple protections:
Pulse-by-pulse overcurrent protection (OCP)
Overload protection (OLP) with auto restart
Latching overvoltage protection (OVP)
Undervoltage lockout (UVLO) with hysteresis
Latching thermal shutdown (TSD)
