Application Examples
• ADAS sensors, cameras, and radars
• Car infotainment, instrument clusters, BCM
(Body Control Modules), etc.
• Automotive applications requiring high
efficiency, superior reliability, and
greater compactness
Availability: In mass production
Nano Pulse Control™ refers to ultra-fast pulse
control technology achieved by combining three
advanced analog technologies, circuit design,
layout, and processes utilizing ROHM's vertically
integrated production system. This allows a
single power supply IC to convert from a
high voltage to a low value, which previously
required two or more ICs, contributing to greater
miniaturization and simplification in applications
that drive both 12V (such as gas-powered
vehicles, xEVs) and 48V systems (such as mild
hybrid vehicles, industrial robots, and base station
sub-power supplies).
Primary
In a power supply IC, the side in charge of first
stage conversion from a power source such as
a battery is called the primary. Similarly, the side
responsible for second stage conversion is called
the secondary.
DC/DC Converter
A type of power supply ICs that convert one
DC voltage to another. Also called switching
regulators, generate an output voltage through
switching operation. They are characterized by
high power conversion efficiency and are available
in two types: a step-up (boost) configuration
that increases the voltage and step-down (buck)
topology that reduces the voltage.
