The Power Integrations TOP221YN is a three-terminal monolithic IC that integrates a power MOSFET, PWM controller, high voltage start-up circuit, loop compensation, and fault protection circuitry. It is designed for offline switched-mode power supply applications.
This device supports multiple topologies including Flyback, Forward, Boost, and Buck. It features a voltage rating of 700V and operates at a frequency of 100kHz, delivering up to 12W of power. The TOPSwitch-II family, to which this part belongs, offers cost-effectiveness and enhanced performance for various applications.
The TOP221YN is housed in a TO-220-3 package, suitable for through-hole mounting. It includes built-in auto-restart and current limiting, along with latching thermal shutdown for system-level protection. The internal lead frame design helps dissipate heat directly to the board, potentially eliminating the need for a heatsink in lower power applications.
