TOP223YN

POWER INTEGRATIONS · AC-DC Controllers And Regulators · TO-220

TOP223YN from POWER INTEGRATIONS, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CONTROL input Error amplifier and feedback current input for duty-cycle control; it also provides the internal shunt regulator connection for bias during normal operation and is the connection point for the supply bypass and auto-restart/compensation capacitor.
2 SOURCE power_in Output MOSFET source connection for high-voltage power return and the primary-side circuit common and reference point; the tab is internally connected to this pin.
3 DRAIN passive Output MOSFET drain connection that provides start-up bias current through an internal switched high-voltage current source and serves as the internal current sense point.
