TNY268PN Off-line Switcher IC

The TNY268PN Off-line Switcher IC is a high-efficiency integrated circuit designed for off-line switch-mode power supplies (SMPS) and low-power AC-DC converter applications. Part of the TinySwitch family, this IC combines a high-voltage power MOSFET switch, PWM control, and protection circuitry into a single chip, significantly simplifying power supply design while improving performance and reliability.

With built-in protections such as over-current, over-temperature, and auto-restart, TNY268PN delivers stable power conversion with reduced external components. It is ideal for use in adapters, chargers, LED drivers, consumer electronics, and industrial power modules requiring compact, efficient, and cost-effective power solutions.
