●General
Description
ROHM’s high efficiency step-down switching regulator
BD9134MUV is a power supply designed to produce
3.3 volts from 5 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/Nch FET)
TM
and SLLM (Simple Light Load Mode)
Incorporates soft-start function.
Incorporates thermal protection and UVLO
functions.
Incorporates short-current protection circuit with
time delay function.
Incorporates shutdown function
