TNY275PN Power Integrations Off Line Switcher IC

TNY275PN Power Integrations Off Line Switcher IC 

The TNY275PN is a highly integrated 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 TNY275PN is ideal for low to medium power AC-DC converters, offering high efficiency, ultra-low standby power consumption, and excellent reliability. It is widely used in chargers, adapters, standby power supplies, consumer electronics, and auxiliary power modules.
