Sanken STR-A6252M
20W 67kHz Flyback Switching Regulators
FEATURES AND BENEFITS
67 kHz PWM with ±5% frequency jittering for EMI noise filtering and cost reduction Rugged 650 V avalanche-rated MOSFET:● Simplified surge absorption
● No VDSS derating required Low RDS(on) : 2.8 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 in 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) STR-A6252M Universal-Input 20 W 67 kHz Flyback Switching Regulators The STR-A6252M is a 67 kHz PWM topology (with ±5% frequency jittering for minimum EMI) regulator specifically designed to satisfy the requirements for increased integration and reliability in flyback converters.
