DK1203 – DIP

درباره این محصول

• Introduction
• The DK1203 is a secondary side flyback type AC-DC Switch Mode Power Controlling IC. With integrated 700V high voltage power transistor,patented self-power supply circuit and integrated MOS circuit design, lots of external components are saved, transformer design is simple, only two windings is needed for the transformer in isolated output circuit.
• Description
• Input voltage 85V to 265V full voltage range
• Built-in 700V power tube
• Built-in self-powered circuit (patented), no auxiliary winding power supply
• Integrated self-starting circuit
• Current mode PWM control
• VCC operating voltage range of 4V to 6V
• 65Khz switching frequency
• Auto-enter skip cycle mode at light load
• Over-temperature, over-current, over-voltage, overload protection
• Standby power consumption is less than 0.3W
• Frequency jitter reduces EMI filtering cost
