General Description

Key Specifications

 Input Voltage Range

BD9120HFN:

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.
