4.5-13.2V 2A 1ch Buck converter - BD9141MUV

ROHM's high efficiency step-down switching regulator BD9141MUV is a power supply designed to produce a low voltage including 5.0 / 3.3 volts from 2 lithium cell 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.
