LINEAR TECHNOLOGY LTC7812IUH#PBF 芯片, 直流/直流转换器, 同步升压-降压, QFN-32
The is an adjustable output synchronous boost and buck DC to DC switching regulator controller in 32 pin QFN package. This high performance controller drives all N channel power MOSFET stages. It contains independent step up boost and step down buck controllers that can regulate two separate outputs or be cascaded to regulate an output voltage from an input voltage that can be above, below or equal to output voltage. The LTC7812 can operate from an input supply as low as 2.5V after start-up. The 33µA no load quiescent current extends operating run time in battery powered systems. Unlike conventional buck-boost regulators, the LTC7812"s cascaded boost and buck solution has continuous, non-pulsating input and output currents which substantially reduces voltage ripple and EMI. This controller has independent feedback and compensation points for boost and buck regulation loops, enabling a fast output transient response that can be easily optimized externally.
