Introduction to TOP222YN

The TOP222YN is a monolithic integrated, off-line switcher from Power Integrations. It is designed to provide a simple, cost-effective solution for low power switch mode power supplies, meeting ENERGY STAR requirements for efficiency. The device includes an integrated active ORing switch that enables it to be used as a main switcher in an AC-DC application, taking the load from a DC-DC converter to provide a fast, efficient and reliable power solution.

TOP222YN Application Field

The TOP222YN is suitable for a variety of AC-DC applications, such as desktop computers and workstations, display monitors and televisions, battery backup systems, notebook computers, and Point-of-Loads (POL) supplies. It is especially well suited for applications that require low stand-by power consumption, smart power delivery, and low EMI solutions.

TOP222YN Working Principle

The TOP222YN is based on a TOPSwitch-GX integrated circuit, consisting of a high-voltage power MOSFET switch and an integrated control circuit. When an AC voltage is applied, the device is quiescent until the AC line voltage reaches the start threshold. The control system then synchronizes to the AC input voltage, typically less than 1ms, and triggers an ON pulse to enable the high-voltage Power MOSFET switch. The TOPSwitch-GX then operates like an ON/OFF switch and regulates the output voltage with a pulse width modulation circuit that senses the output voltage. The switching action keeps the output voltage in balance, while the PWM control loop eliminates voltage overshoots and undershoots while providing a fast, stable response to load changes.Additionally, the device incorporates an intelligent circuitry that prevents the Power MOSFET from turning on in an over-voltage condition, providing protection from incorrect AC mains connection and eliminating the need for crowbar protection circuitry. The device also includes protection from surges, spikes, and brownouts.

Conclusion

The TOP222YN has become a popular solution for low-power switch-mode power applications, due to its cost-effectiveness, high efficiency, and ENERGY STAR requirements compliance. The device uses a TOPSwitch-GX integrated circuit to provide a fast, efficient and reliable power solution, along with an integrated active ORing switch to take the load from a DC-DC converter, and protection from surges, spikes and brownouts. The TOP222YN is suitable for a variety of applications, making it an ideal choice for customers looking for an easy, reliable switch-mode power supply solution.
