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) All performance characteristics given are typical values for circuit or system baseline design only and are at the nominal operating voltage and an ambient temperature of +25°C, unless otherwise stated.
Datasheet 28103.
44-6b 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 Package DIP-8 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) Approximate Scale 1:1 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, FEATURES AND BENEFITS provide high reliability of system design.
100 kHz 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.
