TNY268PN Power Integrations Off Line Switcher with Low Power IC

TNY268PN Power Integrations Off Line Switcher with Low Power IC 

The TNY268PN is a highly integrated low-power AC-DC off-line switcher IC from Power Integrations’ TinySwitch family, designed to build compact, efficient, and low-cost switch-mode power supplies (SMPS). It integrates a high-voltage power MOSFET, PWM controller, oscillator, soft-start, and comprehensive protection features into a single device, significantly reducing external component count and simplifying power supply design.

The TNY268PN is ideal for low-power AC-DC converters and standby power supplies, offering high efficiency, ultra-low standby power consumption, and excellent reliability. It is widely used in phone chargers, adapters, standby power modules, IoT devices, consumer electronics, and auxiliary power supplies.
