PMIC, or Power Management IC, is a type of integrated circuit that helps manage the power usage of electronics. They are used in a variety of applications, and one of the most popular types is the AC/DC Converters and Offline Switchers. The TNY254GN is one such device, and it offers a number of benefits for those working in these applications.

Overview of AC/DC Converters and Offline Switchers

AC/DC converters are devices that convert alternating current (AC) to direct current (DC). AC to DC conversion is necessary in many electronic devices and appliances, including computers, mobile phones, and video game consoles. Offline Switchers are switches that control and switch the power between multiple sources. They are used in a variety of applications, from controlling the flow of power in industrial, medical, and automotive electronics to powering LED lights.
