Overview:
JT3026 is a high performance peak current mode PWM controller with innovative patented topology Structure, suitable for forming a simple flyback AC/DC converter Changer. A 700V power switch with high cost performance Tube, PWM control circuit, oscillator, anti-overload protection Saturation and other circuits are integrated into the chip and high prices are used Bipolar production process reduces the products production this. The product is wide in 85VAC to 265VAC input Power up to 12W in voltage range. In the adapter, electricity Wide range of electronic devices such as pool chargers and set-top boxes Applications.

Features:
■ Integrated 700V high voltage power switch tube, no external
   Power tube
■ Built-in slope compensation function to ensure that the output is large
   Stability of the system compared to the situation;
■ Complete the use of the amplification of the internal power tube
   Move, reduce the power consumption of starting resistance;
■ Independent upper current detection controller, real-time processing
   Overcurrent and overload of the controller
■ Undervoltage lockout and overvoltage protection for power supply voltage
■ Integrated thermal protection, ramp current drive circuit;
■ Built-in temperature-compensated current limiting resistor,
   Accurate current limit;
■ Off-period emitter bias voltage output improves performance
   The pressure resistance of the tube;
■ Low starting current and operating current
■ Low output power consumption, no output
   power consumption can be lower than 0.35W
