BD9106FVM BD9107FVM BD9109FVM BD9110NV BD9120HFN
●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
