Buck-Boost µModule Regulator
FEATURES
DESCRIPTION
The LTM®4712 is a high efficiency buck-boost µMod-
ule® (micromodule) regulator. The switching controller,
power switches, inductor and support components are
included in the package. The complete design requires
only a few external components, including a resistor to
set frequency, a resistor to set output voltage, input, and
output capacitors, a sensing resistor to achieve input or
output average current regulation. The LTM4712 operates
over a 5V to 36V input voltage range and can regulate
output voltages between 1V and 36V.

The LTM4712 supports selectable forced continuous
mode (FCM)/pulse-skipping mode (PSM) operation. The
current mode control enables a fast transient response
to line and load changes without sacrificing stability. The
SYNC input and CLKOUT output allow easy synchroniza-
tion. It supports multi-phase parallel operation for high
power applications.
