Datasheet
2.7V to 5.5V, 2.0A 1ch
Synchronous Buck Converter integrated FET
BD9130NV
âGeneral Description
ROHMâs high efficiency step-down switching regulator
BD9130NV is a power supply designed to produce a
low voltage including 1 volts from 5.5/3.3 volts 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.
âFeatures
â Offers fast transient response with current mode
PWM control system.
â Offers highly efficiency for all load range with
synchronous rectifier (Nch/Pch FET)
and SLLMTM(Simple Light Load Mode)
â Incorporates soft-start function.
â Incorporates thermal protection and ULVO
functions.
â Incorporates short-current protection circuit with
time delay function.
â Incorporates shutdown function
