PMICs, or Power Management Integration Circuits, are a type of integrated circuit (IC) responsible for the regulation of power on a device and provide protection from power surges and other power-related anomalies. AC DC Converters, Offline Switchers, and TNY267GN are all common types of PMIC components. In this article, we will discuss the application field and working principle of TNY267GN.

TNY267GN is a cost-efficient, monolithic offline switcher IC. It is typically used to reduce the noise level and power consumption of a device, as well as to increase efficiency when used in isolated offline power conversion applications. The device\'s high-efficiency resonant circuitry combined with its low quiescent current ensures minimal energy waste in the process.

The output application of the TNY267GN is a buck-type converter, which allows the user to adjust the output voltage and current. The input voltage range is from 4.5V to 40V, making it suitable for a wide range of applications. The maximum output power is 40W, which makes the device suitable for various applications. Some common applications are adapters, charger, motor driver, and LED lighting.

In terms of working principle, the TNY267GN is based on the buck topology. In the buck topology, a power switch is used to either connect or disconnect the voltage supply to the output stage. When the switch is turned on, the voltage supply is connected to the output stage and the output voltage is determined by the input voltage and the switch\'s on-time ratio. When the switch is off, the voltage supply is disconnected and the Load is powered by the output capacitor\'s stored energy.

Apart from the voltage regulation feature, the TNY267GN also provides enhanced safety features such as under voltage lockout, short over-current protection, over temperature protection, and a dual-enable pin for auto power off. This makes the device suitable for both mobile and stationary applications.

In conclusion, the TNY267GN is an offline switcher IC from PMICs family. It is suitable for various offline applications, as it provides cost-efficiency, low noise, low power consumption, and enhanced safety features. The working principle of the TNY267GN is based on a buck topology, where a power switch is used to either connect or disconnect the voltage supply to the output stage.
