BD9120HFN

高效率降压开关稳压器具有内置功率MOSFET High-efficiency Step-down Switching Regulators with Built-in Power MOSFET

●General Description

ROHM’s high efficiency step-down switching regulators BD9106FVM, BD9107FVM, BD9109FVM, BD9110NV, are the power supply designed to produce a low voltage including 1 volts from 5/3.3 volts power supply line. Offers high efficiency with our original pulse skip control technology and synchronous rectifier.  Employs a current mode control system to provide faster transient response to sudden change in load.
