Step Down (Buck) Regulators
Buck Regulators: The Buck regulator is a DC-to-DC power regulator , which steps down voltage from its input (supply) to its output (load). It has two kinds of structures: converter and controller.
The synchronous switch controller can drive the external MOSFET directly, so it can provide the wider voltage, higher current/ higher power with better thermal performance.. The synchronous converter, which integrates ultra-low Rdson power MOSFET, provides a high-efficiency power conversion solution with high integration, high density and simplified total solution BOM for the system.
