JT3026J

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:
