BD9120HFN
BD9120HFN is Synchronous Buck Converter manufactured by ROHM.
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, Microputer and ASIC
