TOP262EN General Description

The TOP262EN is a high-performance Quasi-Resonant (QR) PWM controller designed for offline power supplies in a wide range of applications. It features a built-in 700V MOSFET that allows it to operate with input voltages up to 265V AC. The device utilizes QR technology to achieve higher efficiency and lower electromagnetic interference (EMI) compared to traditional PWM controllers.The TOP262EN offers a range of protection features, including overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown protection. These safeguards help protect the power supply and the connected equipment from damage in case of fault conditions. The device also includes a frequency jittering function that further reduces EMI emissions.The controller can operate in either continuous or discontinuous conduction mode, providing flexibility for different load conditions. It also includes a power-saving feature that helps reduce power consumption during standby or light load operation.In summary, the TOP262EN is a high-performance QR PWM controller with a built-in MOSFET, offering protection features, improved efficiency, and reduced EMI. Its versatile operation modes and power-saving capabilities make it an ideal choice for a wide range of offline power supply applications
