design features 2.7V to 40V Monolithic Buck-Boost DC/DC Expands
Input Capabilities, Regulates Seamlessly through
Automotive Cold-Crank and Load-Dump Transients
John Canfield Handheld devices, industrial instruments and automotive electronics all demand power
supply solutions that can support an expansive range of input voltages resulting from
automotive input voltage transients, resistive line drops and a wide variety of power
sources. As a further design challenge, applications often require a variety of regulated
voltage rails, including some that fall within the input voltage range. The LTC3115-1
buck-boost DC/DC converter, with its wide 2.7V to 40V input and output voltage
capability, high efficiency, small footprint and seamless transition between step-up and
step-down modes of operation, easily meets the requirements of such applications.
For automotive electronics, the LTC3115-1
provides uninterrupted operation through
load dump transients and even the harshest cold-crank conditions. Its programmable switching frequency optimizes
efficiency and supports operation at 2MHz
to ensure that switching noise and harmonics are located above the AM broadcast
band. The LTC3115-1 employs a proprietary low noise PWM control algorithm
that minimizes electromagnetic emissions over all operating conditions even
during transitions between the step-up
and step-down modes of operation and
over the full range of load current. An
internal phase-locked loop allows switching edges to be synchronized with an
external clock for further control of …
