2.55-5.5V 0.4A/0.3A 2ch Buck converter - BD91501MUV

ROHM's high efficiency dual step-down switching regulator BD91501MUV is a 2ch output power supply designed to produce a low voltage including 2.55V/0.4A and 1.8V/0.3A from 3.3V 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.
