TOP224YN Description

Short technical summary and product information.

The TOPSwitch-II family, including the TOP224YN from Power Integrations, offers a cost-effective solution for switched-mode power supplies. This three-terminal monolithic IC incorporates a power MOSFET, PWM controller, high-voltage startup circuit, loop compensation, and fault protection circuitry.

Key features include built-in auto-restart and current limiting, along with latching thermal shutdown for system-level protection. The TOP224YN supports various topologies such as Flyback, Forward, Boost, or Buck, and works with primary or opto feedback. It is stable in both discontinuous and continuous conduction modes.

This device offers significant advantages in reducing component count and cost, making it competitive with linear solutions above 5W. It achieves up to 90% efficiency with very low AC/DC losses. The internal lead frame design utilizes pins to transfer heat directly to the board, often eliminating the need for a heatsink.

The TOP224YN is available in TO-220, 8L PDIP, and 8L SMD packages, supporting through-hole mounting. It is suitable for applications requiring up to 150W output power for 100/115/230 VAC input or up to 90W for universal 85-265 VAC input, provided appropriate heat sinking is used.
