General Description
ROHM’s high efficiency step-down switching regulators
(BD9106FVM,BD9107FVM,BD9109FVM,BD9110NV,B
D9120HFN) are the power supply designed to produce
a low voltage including 1 volts from 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.
Features
Offers fast transient response with current mode
PWM control system.
Offers highly efficiency for all load range with
synchronous rectifier (Nch/Pch FET)
and SLLMTM (Simple Light Load Mode)
Incorporates soft-start function.
Incorporates thermal protection and ULVO
functions.
Incorporates short-current protection circuit with
time delay function.
Incorporates shutdown function
Application
Power supply for LSI including DSP, Micro computer
and ASIC
