2.7V to 5.5V, 2.0A 1ch
Synchronous Buck Converter Integrated FET
BD8960NV
●General Description
ROHM’s high efficiency step-down switching
regulator BD8960NV 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
synchronous rectifier. Employs a current mode
control system to provide faster transient response
to sudden change in load.
●Features
 Offers fast transient response with current mode
PWM control system.
 Offers highly efficiency for all load range with
synchronous rectifier (Nch/Pch FET)
 Incorporates soft-start function.
 Incorporates thermal protection and ULVO
functions.
 Incorporates short-current protection circuit with
time delay function.
 Incorporates shutdown function
