ROHM has developed a new lineup of 12
automotive primary DC/DC converters. The
BD9P series is optimized for ADAS (Advanced
Driver Assistance System) sensors, cameras,
and radars, along with car infotainment and
instrument clusters.
In recent years, the continued electrification
of vehicle systems has increased. Combined
with the limited amount of power available, this
trend emphasizes the need for lower power
consumption. At the same time, the output
voltage from the batteries and generators can
vary widely, demanding a versatile power
supply solution.
The need for fast response to provide stable
operation and higher power conversion
efficiency is crucial, making it difficult to meet
with conventional power supply integrated
circuits. The new product adopting original
advanced power supply technology, Nano
Pulse Control
TM
, enables high-speed operation
at 2.2MHz that will not interfere with the AM
radio band (1.84MHz max.) while achieving a
high step-down ratio. This makes it ideal– for
automotive applications.
Fast response and high efficiency contribute
to lower power consumption
