DESCRIPTION
The
LTM
®
8057
is a 2kV AC isolated flyback µModule
®
(micromodule) DC/DC converter. Included in the package
are the switching controller, power switches, transformer,
and all support components. Operating over an input volt-
age range of 3.1V to 31V, the LTM8057 supports an output
voltage range of 2.5V to 12V, set by a single resistor. Only
output and input capacitors are needed to finish the design.
Other components may be used to control the soft-start
control and biasing.
The LTM8057 is packaged in a thermally enhanced, com-
pact (9mm

11.25mm
×
4.92mm) overmolded ball grid
array (BGA) package suitable for automated assembly
by standard surface mount equipment. The LTM8057 is
available with SnPb or RoHS compliant terminal finish.
