Input voltage range  
BD9120HFN:  
ROHM’s high efficiency step-down switching regulators  
(BD9106FVM,BD9107FVM,BD9109FVM,BD9110NV,B  
D9120HFN) 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.
