TYPICAL APPLICATION
DESCRIPTION
The LTC ? 3631 is a high voltage, high efficiency step-down
DC/DC converter with internal high side and synchronous
power switches that draws only 12μA typical DC supply
current at no load while maintaining output voltage
regulation.
The LTC3631 can supply up to 100mA load current and
features a programmable peak current limit that provides
a simple method for optimizing efficiency in lower current
applications. The LTC3631’s combination of Burst Mode ?
operation, integrated power switches, low quiescent cur-
rent, and programmable peak current limit provides high
efficiency over a broad range of load currents.
With its wide 4.5V to 45V input range and internal overvolt-
age monitor capable of protecting the part from 60V surges,
the LTC3631 is a robust converter suited for regulating a
wide variety of power sources. Additionally, the LTC3631
includes a precise run threshold and a soft-start feature
to guarantee that power system start-up is well-controlled
in any environment.
The LTC3631 is available in the thermally enhanced
3mm × 3mm DFN and MS8E packages.
