Buck-Boost Regulators
Buck-Boost Regulators: thanks to the step-up/step-down topology, it can flexibly support a wide input voltage range and wide output voltage range. It is able to effectively regulate the output voltage no matter it is higher, lower or equal to the input voltage. The synchronous switch controller can drive the external MOSFET directly, so it can provide the wider voltage, higher current/ higher powe 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.
