Synchronous Buck Converter with Integrated FET
BD9106FVM BD9107FVM BD9109FVM BD9110NV BD9120HFN
General Description The BD9106FVM, BD9107FVM, BD9109FVM, BD9110NV, and BD9120HFN are ROHM’s high efficiency step-down switching
regulators designed to produce a voltage as low as 1V from a supply voltage of 3.3V or 5.0V. It offers high efficiency by using synchronous switches and provides fast transient response to sudden load changes by implementing current mode control.
Features Fast Transient Response because of Current Mode Control System High Efficiency for All Load Ranges because of Synchronous Switches (Nch and Pch FET) and SLLMTM (Simple Light Load Mode) Soft-Start Function Thermal Shutdown and ULVO Functions Short-Circuit Protection with Time Delay Function Shutdown Function
Application Power Supply for LSI including DSP, Microcomputer and ASIC
