The TNY274PNAU is part of the TinySwitch-III series of offline Switchers and AC/DC converters produced by Power Integrations. This series of products is designed to offer performance, cost, and size advantages over traditional offline switchers and AC/DC converters. This particular series of product is well suited to applications such as medical, consumer, industrial, and telecom.

The TNY274PNAU is capable of providing a wide range of AC/DC Conversion and offline switching solutions. It is designed to provide high efficiency switching and level-shift control, while also providing protection and overload capability. The voltage and current range of the TNY274PNAU is from 3.6V to 20V and up to 4A. The device features a soft-start and advanced current limiting for low inrush current and smooth power up.

The Working Principle of the TNY274PNAU is relatively straightforward. It is made up of a power switch, a transformer, and a diode bridge, which are connected in a half-bridge topology. The power switch is driven by a charge pump, which is then controlled by a control chip. The output of the TNY274PNAU is regulated by an internal voltage monitor, which monitors the output voltage and adjusts the switching frequency accordingly, to provide the desired output voltage.

The TNY274PNAU is an excellent choice for multiple applications, as it offers high efficiency, low inrush current, and isolation, while being relatively small and cost effective. As it is part of the TinySwitch-III series, it can be used in applications such as medical, consumer, industrial, and telecom applications, allowing for a wide range of use.
