BD9152MUV
4.5-5.5V 1.5A/1.5A 2ch Buck converter
BD9152MUV
4.5-5.5V 1.5A/1.5A 2ch Buck converter
ROHM's high efficiency dual step-down switching regulator BD9152MUV is a power supply designed to produce a low voltage including 3.3, 1.2volts from 5.0volts 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.
