2.5-4.5V 0.6A 1ch Buck Converter - BD9161FVM-LB

This is the product guarantees long life cycle in Industrial market.
ROHM’s high efficiency step-down switching regulator BD9161FVM-LB is a power supply designed to produce 1.2volts (low voltage) from 3.3volts 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.
