TNY266PN Power Integrations Off Line Switcher IC

TNY266PN Power Integrations Off Line Switcher IC 

The TNY266PN is a highly integrated low-power AC-DC off-line switcher IC from Power Integrations’ TinySwitch family, designed to build compact, efficient, and cost-effective switch-mode power supplies (SMPS). It combines a high-voltage power MOSFET, PWM controller, oscillator, soft-start, and comprehensive protection circuitry in a single device, significantly reducing external components and simplifying power supply design.

The TNY266PN is ideal for low-power AC-DC converters and standby power supplies, offering high efficiency, ultra-low standby power consumption, and long-term reliability. It is widely used in chargers, adapters, auxiliary power supplies, consumer electronics, and IoT devices.
