BD9161FVM
2.5-4.5V 0.6A 1ch Buck converter

ROHM's high efficiency step-down switching regulator BD9161FVM is a power supply designed to produce 1.2volts (low voltage) from 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.
