4.5-5.5V 1.5A/1.5A 2ch Buck converter - BD9152MUV

ROHM's high efficiency dual step-down switching regulator BD9150 / 52MUV 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.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
