TOP222YN

The TOP222YN is a member of the TOPSwitch-II family of integrated circuits produced by Power Integrations. It is primarily used for designing cost-effective and efficient switch-mode power supplies (SMPS). The device integrates a high-voltage power MOSFET, PWM controller, fault protection, and other necessary control circuitry into a single package, minimizing the need for external components and reducing the overall size and cost of power supply designs.
Key features of the TOP222YN include its ability to operate over a wide input voltage range, high efficiency due to low standby power consumption, and built-in protection features such as overcurrent, overtemperature, and overvoltage protection. The device can be used in applications such as AC-DC power supplies for consumer electronics, adapters, and industrial control systems. Its robust design supports both flyback and forward converter topologies, providing designers with flexibility in circuit configuration. The “YN” suffix indicates the package type, which is typically a TO-220, making it suitable for high-power applications.

The TOP222YN is a member of the TOPSwitch-II series, which is a family of integrated off-line switcher ICs used for power supply applications. It typically comes in a TO-220 package with three pins.
1. D (Drain): This is the high voltage power MOSFET drain pin. It is connected to the primary winding of the transformer and carries the switched voltage.
2. S (Source): This is the power MOSFET source pin and control circuit common. It is connected to the source of the internal MOSFET and serves as the return path for the control logic and the reference for the current limit.
3. C (Control): This is the control pin used for feedback and to set the current limit. It is connected to an external resistor for setting the current limit and can be used to connect an optocoupler for feedback from the secondary side of the power supply.
These pins make the TOP222YN suitable for use in low power offline switcher applications such as battery chargers and standby power supplies.
