TNY376GN Working Principle

The functioning of the TNY376GN is based on a single-stage power conversion mechanism whereby a boost converter feeds the input source with a sufficiently high voltage, which is then converted to a low voltage by a two-level synchronous rectifier. The output is provided by an output capacitor, which acts to smooth the current ripple and provide the power supply to the load.

The TNY376GN uses a PWM circuit to control the conduction and switching of the internal power switches with extremely high accuracy. The advantage of this control mode is that it allows for a high efficiency, low power consumption and a wide temperature range. Furthermore, the device has a built-in output voltage automatic reset circuit, which prevents over-voltage and under-voltage events.

Conclusion

In conclusion, the TNY376GN is an advanced PMIC designed for a variety of AC/DC conversion and offline switching applications. It features a single-stage power conversion mechanism and provides high efficiency, low power consumption and wide temperature range. This makes it suitable for use in industrial and consumer electronics, portable audio devices and laboratory equipment.
