INN3673C-H602-TL Working Principle

The Synchronous Rectification Buck converter used in INN3673C-H602-TL is based on a MOSFET switching with one to two MOSFETs in a bridge configuration. It is a DC-DC converter allowing the transformation of a low voltage DC input to a higher voltage DC output.Essentially, the INN3673C-H602-TL uses its two-phase control to reduce electromagnetic interference (EMI) and improve efficiency. Its innovative two-phase architecture enables the device to deliver an output voltage that is easily adjustable over a wide range while maintaining a high efficiency.The main working principle of INN3673C-H602-TL is that it controls the S/Phase signals to periodically generate a switching voltage, which charges the inductor. As the switch turns on, the current stored in the inductor is passed to the output capacitor, maintaining the output voltage.When the S/Phase signals switch state, the charge stored in the inductor is transferred instantaneously to the other winding. This process of switch on and off creates an efficient power transfer from the input to the output.The current is regulated by the device\'s internal compensation and is held constant until the next switching period. This process repeats until the input voltage has been reduced to a certain level, thus ensuring a stable output voltage for various applications.

Conclusion

The INN3673C-H602-TL is a two-phase synchronous rectification buck converter, widely used in various applications. Its wide voltage range, high efficiency and low quiescent current make it an ideal choice for many applications. Furthermore, its main working principle is based on the two-phase control which enables the device to deliver an output voltage that is easily adjustable over a wide range while maintaining a high efficiency.
