Working Principle

The LTC3407IDD-2#PBF is a synchronous DC/DC converter, meaning that it relies on parallel switching of the high side and low side to transfer power from input to output. It uses a constant on-time control scheme and is enabled by the EN pin, which turns on the power switches and the low-side switch. When the high side switch and the low side switch are enabled by the EN pin, current is drawn from the input and transferred through the switching network to the output voltage. The operating frequency of the converter is dependent on the timing components and can be adjusted depending on the output requirements of the application.

The LTC3407IDD-2#PBF is an efficient, economical and robust device for a variety of applications and systems that require steady power supply. Its features, combined with its shielding and stable performance, makes it a perfect choice for power and voltage regulation.
