The working principle of the INN3276C-H204-TL AC-DC offline switcher is based on the principle of pulse width modulation (PWM). At the input end of the SMPS, an AC voltage is input. After being rectified by the diode and filtered by the capacitor, a DC voltage is obtained. Then the voltage is sent to the internal IC of the SMPS. The work of the SMPS IC is to analyze the input voltage, convert it into a corresponding output voltage, compare the output voltage with a reference voltage, open and close the MOSFET through the Pulse Width Modulation (PWM), and then adjust the on and off of the MOSFET to control the output voltage of the switching power supply.

In conclusion, the INN3276C-H204-TL AC-DC offline switcher is a high-performance integrated AC-DC power management circuit, which has wide application field and easy operation. With its various functions, it can provide more reliable power supply system for various different products.
