60 Watt Laptop Battery Charger

60 Watt Laptop Battery Charger
The circuit is designed for laptop battery charger with 20V output voltage. This circuit uses TOP 246 Y made ​​by Power integrations. TOP 246 Y eliminates half the discrete components compared with the UC3842. As promised Power Integration, this IC is more reliable, has a smaller form, reducing the time in designing and saving costs. (more…)

60 Watt Switching Power Supply

60 Watt Switching Power Supply
The scheme is a classical flyback power supply for PWM UC3842. Since the scheme's base power supply output parameters can be easily converted to the necessary. As an example, for the consideration of selected Power supply for  Notebook Power 20V 3A. If necessary, you can get some voltage related or independent. (more…)
