Boost Regulators: is a DC-to-DC power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load) 

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 BOMfor the system.
