DESIGN FEATURESвЂ‰L 36V, 3.5A DC/DC Buck Regulators
for Automotive, Industrial and Wall
Adapter Applications Offer High
Efficiency in a Small Package
by Kevin Huang Introduction
Automotive batteries, industrial power
supplies, distributed supplies and
wall transformers are all sources of
wide-ranging, high voltage inputs. The
easiest way to step down the voltage
from these sources is with a high voltage monolithic step-down switching
regulator that can directly accept a
wide input range and produce a wellregulated output. The LT3680 and
LT3693 are new step-down switching
regulators that accept inputs up to 36V
and provide excellent line and load
regulations and dynamic response.
Both regulators offer high efficiency
solutions over wide load range. The
LT3680 adds low ripple Burst ModeВ®
operation to maximize efficiency at
light load currents. LT3680 and LT3693 Features
Available in either a 10-pin MSOP …
