The TOPSwitch-II family, including the TOP223YN, represents a cost-effective and enhanced solution for switched-mode power control. These monolithic ICs integrate a power MOSFET, PWM controller, startup circuit, loop compensation, and fault protection circuitry into a three-terminal package.
The TOP223YN is designed for applications requiring low component count and high efficiency, achieving up to 90% AC/DC conversion efficiency. It supports various topologies including Flyback, Forward, Boost, or Buck, and works with primary or opto feedback. The device is stable in both discontinuous and continuous conduction modes.
Output power capabilities vary by package and input voltage. For the TO-220 package, maximum output power is up to 150W for 100/115/230 VAC input and 90W for 85-265 VAC universal input. For the 8L PDIP or SMD package, maximum output power is 30W for 100/115/230 VAC input and 25W for 85-265 VAC input. These power ratings assume appropriate heat sinking and specific PCB copper conditions.
Key features include built-in Auto-Restart and Current Limiting, as well as Latching Thermal Shutdown for system-level protection. The source-connected tab on the TO-220 package aids in low EMI. Circuit simplicity and available design tools can reduce time to market for designs utilizing this component.
