Description
The STR-A6259H is a 100 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. It incorporates a primary control and drive circuit with an avalanche-rated power MOSFET. Covering the power range from below 17 watts for a 230 VAC input, or to 13 watts for a universal (85 to 264 VAC) input, this device can be used in a wide range of applications, from DVD players and VCR player/recorders to ac adapters for cellular phones and digital cameras. An auto-burst standby function reduces power consumption at light load, while multiple protections, including the avalanche-energy guaranteed MOSFET, provide high reliability of system design.
Specifications and 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 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)Application Scenarios
The STR-A6259H can be used in a wide range of applications, such as:
