INN3676C-H602-TL application field and working principle can be broadly divided into two categories, PMIC-AC DC Conversions and Offline Switchers.

PMIC-AC DC Conversion

INN3676C-H602-TL is a type of pulse width modulation (PWM) constant voltage power supply component, which is used in PMIC-AC DC Conversions. The component consists of four parts: a rectifier bridge, an Intersil N-Channel MOSFET with NTC thermistor protection, a voltage regulator, and a controller.

The rectifier bridge is used to convert the AC voltage into DC voltage. The Intersil N-Channel MOSFET with NTC thermistor protection is used as a switching regulator to convert the DC voltage into a constant voltage, which can be adjusted using the voltage regulator. The controller is used to regulate the voltage by adjusting the pulse width modulation (PWM).

When the input AC voltage is higher than the preset output voltage level, the controller will adjust the pulse width modulation (PWM) to reduce the output voltage. On the other hand, when the input AC voltage is lower than the preset output voltage level, the controller will adjust the pulse width modulation (PWM) to increase the output voltage.

Offline Switchers

Apart from being used in PMIC-AC DC Conversions, INN3676C-H602-TL is also applicable to the offline switcher. Offline switcher is the interface between the mains power and the low voltage digital controller and it uses active power factor correction to minimize the total harmonic distortion (THD) of the power system.

INN3676C-H602-TL consists of two parts: a rectifier bridge and an N-Channel MOSFET. The rectifier bridge is used to convert the mains power into DC voltage. The N-Channel MOSFET is used to convert the DC voltage into a square wave output, which can be further processed by the low voltage digital controller.

During the switching process, the controller adjusts the pulse width modulation (PWM) to ensure that the output power factor is always close to unity. This helps to reduce the peak current drawn from the mains, thus reducing the total harmonic distortion (THD) of the power system.

In conclusion, INN3676C-H602-TL can be broadly classified into two categories: PMIC-AC DC Conversion and Offline Switchers. In the first category, the component is used to convert AC voltage into a constant voltage. In the second category, the component is used to convert the mains power into a square wave output, which can be further processed by the low voltage digital controller.
