Introduction
The LTC В®3892 is a dual output synchronous buck
controller featuring a wide input voltage range of
4.5V to 60V and an output voltage of 0.8V to 99%
of VIN. The combination of the LTC3892вЂ™s built-in
FET drivers and external FETs yield high efficiency
and high power capability, up to 97% efficiency and
over 60A output current 2. Its robust designвЂ”an IC
operating junction temperature range of вЂ“55В°C to
150В°CвЂ”meets the needs of industrial, automotive,
telecom, military, aerospace and distributed systems. and 3.9ВµA shutdown current, maintaining battery
charge as long as possible. The LTC3892вЂ™s wide
input voltage range satisfies the demanding requirements of industrial and automotive applications,
which are distinguished by their lack of stable, high
quality voltage sources. For example, in automotive
environments, a 12V nominal voltage rail can range
from a low 5V to above 50V during cold starts and
load dumps. The LTC3892вЂ™s ability to sustain the
output in the face of high voltage inputs eliminates …
