AND8145

Quasi−square wave resonant converters AND8145, also known as quasi−resonant (QR) converters, allow designing flyback Switch−Mode Power Supplies (SMPS) with reduced Electro−Magnetic Interference (EMI) signature and improved efficiency. Due to the low level of generated noise, AND8145 are therefore very well suited to applications dealing with RF signals, such as TVs. ON Semiconductor NCP1207 is a QR controller that will ease your design of an EMI−friendly TV power supply with only a few additional components, and able to lower its standby power down to 1.0 W.
