4.5V to 13.2V, 2A 1ch
Synchronous Buck Converter with
Integrated FET
BD9141MUV
General Description
The BD9141MUV is ROHM’s high efficiency step-down switching
regulator designed to produce a low voltage including 5.0V/3.3V from 2 lithium cell power supply line. It offers high efficiency by using pulse skip control technology and synchronous switches, and provides fast transient response to sudden load changes by implementing current mode control.
