BD9139MUV
2.7-5.5V 3A 1ch Buck converter
ROHM’s high efficiency step-down switching regulator BD9139MUV is a power supply designed to produce a low voltage including 0.8 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.
