TNY266PN Off-line Switcher IC

The TNY266PN Off-line Switcher IC is a highly integrated power management device designed for off-line switch-mode power supplies (SMPS) and compact AC-DC power conversion applications. Part of the TinySwitch family from Power Integrations, it combines a high-voltage MOSFET switch, PWM controller, and protection circuitry into a single package, reducing external parts count and design complexity.

Engineered for low-to-medium power supplies, the TNY266PN offers efficient power conversion with built-in over-current, over-temperature, and auto-restart protections, ensuring reliable and safe operation. It’s ideal for designing adapters, chargers, LED drivers, standby power supplies, and industrial control modules.
